EM field theory, formulated by a number of prominent theoretical and experimental physicists in the middle – end of the past century, has been based in fact on the Aragoe and Fresnel experiments proving EM radiation to be transverse. By force of this fact, all the theories without exception, as well as all the theoretical applications to radio-location and communication, when obtaining in their intermediate computations a longitudinal wave, have cut it off, meaning its propagation impossible.

On September 20, 1990, in Moscow, in presence of A.F. Marienko, D.E., the senior research fellow of All-Union High Education Problems Research Institute, the electrophysical engineer from Kharkov S.B. Karavashkin, Ms.Sc. demonstrated me his primary experiment on radiation and reception of the longitudinal EM wave.

This experiment was demonstrated by the conventional block-scheme: generator – radiator – receiver-indicator. The circuit was tuned to the frequency 30 kHz with the pass band approximately 5-6 kHz. A device registering the E-field, not accumulating the energy, but having a band-pass filter, served as a receiver. The oscillograph H313 connected with the receiver by the cable PK75 served as an indicator. A closed parallelepiped containing the know-how, as said the author, served as the radiator. All the devices, except the oscillograph, were hand-made in order to serve this experiment.

The author has demonstrated the following effects:

1. The longitudinal EM wave was radiated and received at the distance about three meters (since the room where the experiment was demonstrated was small). The wave amplitude was 3 large points at the screen of oscillograph when the position of voltage divider was 10 and amplification 5 points.
2. When turning the radiator about any edge, the signal amplitude at the oscillograph reduced in approximately 5 times. The radiation direction was approximately 180 degree. The author said, the residual radiation was caused by a very limited space of the room, and this was corroborated by the following experiment.
3. When approaching the hand to the radiating side of radiator, the signal amplitude at the oscillograph increased in a few times. The touching any other planes of radiator gave no effect. If the distance between the radiator and receiver varied while the hand kept approached, then the signal amplitude at the oscillograph varied as this distance. The same, when approaching the hand to the receiver, even without touching, signal amplitude increased abruptly. When I stood between the radiator and receiver, the signal amplitude increased. When the radiator turning about relatively to the receiver, then the approaching my hand to the radiating surface caused the abrupt increase of the signal at the oscillograph. On the whole it corroborates the author’s declaration that the parasitic radiation reflected from the walls takes place.
4. I have checked the accuracy of experiment, whether the signal was received by the receiver. For it, I have put the receiver off the input of oscillograph. The signal completely disappeared. Thus, the experiment was true.
