This effect was discovered when studying the parameters of a flat Tesla coil [1] and consists in an abnormally large amplitude of the output signal obtained in a receiver that does not have the properties of an amplifier in the usual sense of the word. The phenomenon does not fit into the framework of classical electrodynamics and can be explained only from the point of view of generalized electrodynamics [2-3], which assumes the presence of a second magnetic field (MF), as a complement to the first. The experiment presented in this work clearly demonstrates and proves the presence of this field, the corresponding longitudinal wave, shows the possibility of its rather simple detection and subsequent amplification of the received signal. It is based on resonant methods for receiving and transmitting signals, and therefore operates in a certain frequency range (100 kHz), which, however, can be reconfigured to suit any other requests.

The method of signal detection and amplification proposed here can be applied in radio communication devices based on new principles, as well as in devices for obtaining free energy. But to obtain the desired effect, it is necessary to match several components at the same time: the design of the coils, the parameters of the detector and key elements, the parameters of the master generators. Therefore, we will begin the study of this unusual topic in order.

The block diagram of the experimental setup is shown in Figure 1, where the generator G1 and the transmitting oscillatory circuit L1C1 form the signal transmitter. At a distance \(r\) there is a signal receiver, consisting of a receiving oscillatory circuit L2C2, a frequency mixer MP1, which is also a signal detector, a local oscillator G2, a bandpass filter PH1 and a load Rn. A feature of our circuit will be the design of coils L1 and L2, the method of detecting and amplifying the receiving signal.

The design of the transmitting and receiving coils must comply with Tesla's patent [1], and otherwise does not give the desired effect. For example, if they are made in the form of a frame, or an ordinary coil wound on a pipe, then even with the same inductance parameters, the effect will either greatly decrease or completely disappear. An explanation for this phenomenon can be found in [2-3], where the conditions for the appearance of the second MF are given. For example, the second MF should arise at the point of collision of classical magnetic fields, where their total vector is mutually compensated. But it is precisely such a picture that arises in a flat Tesla coil due to the constructive arrangement of its turns, which follows from this saddle-shaped field distribution [4] and anomalous change in the MF strength vector at some distance from its center [5]. It is at this distance that the maximum manifestation of the desired effect begins.

The schematic diagram of the experimental setup is shown in Figure 2 and is divided into two parts. The transmitter is located on the left side, the receiver located at some distance \(r\) is located on the right side. The author's maximum effect was observed at \(r=6\) cm, which decreased in inverse proportion to the square of this distance (preliminarily). The G1 generator uses a standard signal generator, for example: JDS2900. Any other can be used, it is only important that this generator can produce sinusoidal oscillations with adjustable frequency and signal amplitude from 0 to 20V. One of its two outputs is connected directly to the L1C1 circuit, tuned to a resonant frequency of 100 kHz.

The signal from the transmitting circuit is received by the receiving oscillatory circuit L2C2, tuned to approximately the same frequency. By the way, these contours can be exactly the same. And here the most interesting begins further. The signal from this circuit is switched by a chain consisting of a diode detector VD1-VD2 and a key VT1, made on a mosfet transistor and located in the generator G2. This switch and detector form the mixer, and the radiant amplifier, and this is where the whole effect is born. But if you take any diodes and a transistor, then, most likely, nothing will work.

Diodes for the detector.
Schottky diodes work well as diodes VD1-VD2. The best results for the author were obtained with the following diodes: 11DQ06. They are placed two in parallel, as in the diagram. Very good pair of diodes MBR10100, but they should be placed in series. The fact that Schottky diodes work well with a longitudinal wave, and hence with a second MF, is mentioned in [6], where it is indicated that such diodes behave like biological active points. The exception for ordinary diodes is 1N4148, which, although with less efficiency, but work with a radiant. Such diodes should be placed in parallel. With other diodes, you may not achieve the desired effect.

Transistor VT1 for the key.
This transistor is placed in the output stage of the generator G2, whose task is to generate short pulses, with a duty cycle of 2-3%. To do this, the transistor must have a high rate of pulse rise and low output capacitance. The author found the following best option: TF27S60. But here the original element is very desirable, and even better - pick up one transistor from the batch, which will give the maximum amplitude at the output of the circuit. As a last resort, you can put a transistor like this: IRF3205. Generally speaking, the selection of elements VD1-VD2 and VT1 resembles the search for an operating point in the first graphite detector receivers [7] :)

G2 generator.
Such a generator works very well here. It has a fairly stable reference frequency source, it has an output frequency and duty cycle adjustment. For the optimal effect, it is necessary to be able to fine-tune the last parameter, according to the maximum output signal at point 3 (Fig. 2). But as G2, you can use any other generator that has the above parameters.

Low pass filter.
In diagram 2, only the low-pass filter remains unrepresented, consisting of the R1C3 chain, which was structurally represented in Figure 1 as PH1. Its task is to filter out frequencies above 1 kHz. The filter can also be made in another way, for example, in the form of an L-shaped or T-shaped LC circuit. In this case, its tuning becomes more complicated, but the upper frequency cutoff will be much better, and the power bandwidth will be much greater. This version of the filter can be used in free energy devices. For radio communication devices, it is sufficient to apply an RC filter.

At first glance, there is nothing unusual in scheme 2. The signal received by the L2C2 loop is added to the signal generated by the loop itself by pumping it with the VT1 key. The frequency difference obtained using the nonlinearity of the detector diodes passes through the R1C3 filter and is fed to the output of the XS1 circuit. The amplitude of this signal cannot exceed the amplitude on L2 and the supply voltage, but during measurements it turns out that at the output of XS1 we will get the amplitude values of the low-frequency difference signal, several times higher than the maximum calculated ones. Example. The frequencies of the first and second generators are 101 kHz and 100 kHz, respectively. The amplitude of the received signal on the L2 coil is 10V, and the receiver supply voltage (+U) is 4V. At the output of XS1, we can get a sinusoidal voltage with a frequency of 1 kHz and an amplitude of about 31 volts! But there are no elements in the circuit that amplify the low-frequency signal, all elements play a passive role, do not have sections with negative resistance in their current-voltage characteristic and operate in the HF range.

Let's look at the oscillograms of these processes. Here you need to take into account that the oscilloscope does not always correctly display real processes when it comes to the radiant, and you need to make allowances for this. Circuit power: + U = 6V, and the distance between the coils L1 and L2 is 6 cm.

The first waveform (Fig. 3) shows the signal level on the receiving coil L2 when the local oscillator G2, and the switch VT1, are turned off. Its amplitude is 10V. When G2 is connected, the picture changes slightly (Fig. 4), although at a low resolution the signal amplitude remains approximately the same, but at a lower resolution this amplitude is already about 16V (Fig. 5). If we measure the signal at the output of the VT1 key, at point 2, we will find that its amplitude is about 21V, despite the fact that the power supply of this circuit is only 6V, and the transmitter is turned off (Fig. 6). When the latter is turned on, we see a picture of a low-frequency envelope against the background of the key pulses (Fig. 7), and after the filter - the low-frequency signal itself with an amplitude of 31V (Fig. 8). Moreover, this amplitude is already quite real and has been verified by other devices.

The design of coils L1 and L2 must comply with the Tesla patent [1]. At the author's, they were wound with a wire with a diameter of 1 mm (0.6 mm along the core), in a two-start spiral. The length of each wire is 6m. The author connected these wires both in series and in parallel, and when selecting the appropriate resonant capacitors, he did not notice much difference in the communication characteristics. In general, the length and diameter of the wire can be completely different.

Setting up the scheme is carried out in several stages. First you need to set up the transmitter. To do this, a coil L1 is connected to the generator G1, and a capacitor C1 is selected to it so that the resonance in this circuit has maximum values. This can be monitored with an oscilloscope connected to a second coil (L2) located a short distance from the first.

Further, with the transmitting circuit turned on, the receiving oscillatory circuit is tuned by selecting the capacitor C2, according to the maximum amplitude at point 1. In this case, G2 and the key on VT1 must be disabled. After that, the G2 generator and the key are connected, and power is supplied to the circuit, at first small - 3V, which must be gradually increased until the maximum amplitude is reached at point 3. Usually it is 5-6V. The pulse duty cycle of the generator G2 is also selected: first, the duty cycle adjustment knob must be brought to the minimum value, and then increase the pulse duration until the maximum amplitude is reached at point 3. Typical values: 2-4%. It should be noted here that these parameters are adjusted to specific elements of VD1-VD2 and VT1, and when they are replaced, the adjustment will need to be done again.

Since the first and second magnetic fields complement each other and both are always present, but in different proportions, it is impossible to speak about the detection of only the second MF. Both fields are detected, but it is in this design that the circuit extracts the second field component from the general signal and amplifies it in amplitude. The first MT is also detected but not amplified. To obtain the effect presented in this paper, it is necessary to satisfy several conditions that would be optional for a classical magnetic field and would not fundamentally affect the result.

1. The design of the receiving and transmitting coils should be made according to the patent [1]. For example, if the same wire is placed on a ring in the form of a magnetic loop antenna (in the form of a frame), then with the same distances between the receiver and the transmitter, and with almost the same magnetic fields, the communication amplitude will decrease by an order of magnitude.

2. The basis of the detector is Schottky diodes, which work very well with the second MP, and a special transistor for the key. If they are replaced by other, even similar in characteristics, elements, then the amplification effect may disappear. The author experimented with a large number of different types of semiconductors, but the effect was observed only with the grades indicated earlier.

3. According to classical calculations, there should not be any signal amplification in the circuit presented here. After the mixer, the signal can only decrease in amplitude. In reality, one can observe the amplification of the signal after the mixer by several times.

4. If next to the receiver (0.5-1 m) there are sound speakers that are not connected to the circuit in any way, then with a close distance between the receiving and transmitting coils, and the circuit turned on, you can hear the low-frequency sound of the frequency difference in the speakers. Although there are no elements emitting an electromagnetic wave in the circuit. This property is characteristic of the second magnetic field, which generates static electricity in nearby objects.

In this experiment, the author managed to carry out the transmission of an information signal, as well as the transmission of power, using a longitudinal wave and a second magnetic field. This became possible thanks to a new principle for detecting and amplifying this field, the scheme of which is shown in Figure 2.

Using this scheme, you can make a reliable connection at a distance of 1 m, and this despite the fact that the transmitter power, taking into account the resonant circuit, is no more than a few milliwatts, and the receiver does not have a low-frequency resonant amplifier, which usually produces the main gain that provides the sensitivity of the receiver.

According to preliminary data, the dependence of the output signal amplitude (at XS2) on the amplitudes on the transmitting and receiving coils, and on the distance between them, has the following form: \[ U_{xs2} \sim {U_{L1} \cdot U_{L2} \over r^2}\] The inverse quadratic dependence on distance may be different in the far zone, which requires additional research.

A very important characteristic of this type of connection is the resonant nature of the radiator, which consists of a parallel oscillatory circuit. This means that the consumption of the generator G1 with such a radiator will directly depend on the quality factor of the circuit: the higher its quality factor, the lower the consumption. In this case, the radiation power does not change! Thus, the communication range will not depend on the active power developed in the antenna, as it should for classical transverse radio waves, but on the reactive power developed in the transmitting circuit.

With an optimal distance between transmitter and receiver, it is possible to transmit electrical power with great efficiency. This opportunity for research is provided to seekers of free energy.
