This article presents the experimental results of the effect of gas discharge plasma on an acoustic wave. It is shown that after a certain intensity of the acoustic wave, the presence of plasma leads to a decrease in the Q -factor of the acoustic res

International audience; Based on intuitive reasoning and a simple mathematical model, it is shown that the radio frequency electromagnetic radiation in 1-2-MHz range is generated during the propagation of a directed strong shock wave in air. It is du
