摘要

The results of studying the self/non-self-sustained gas discharge (SNSS discharge) excited by microwave beams at high gas pressure (atmospheric or higher than atmospheric) under conditions of a substantially subthreshold radiation power are presented. The discharge has a number of properties that distinguish it from all microwave discharges described in literature. The physical model of the discharge built at the Prokhorov General Physics Institute, Russian Academy of Sciences, describes its excitation at pressures high enough that the frequency of electron-neutral collisions is appreciably higher than the cyclic frequencies of microwaves, and the microwave beam power is much lower than the threshold for the excitation of a self-sustained plasma formation. For the first time, the article presents the results of "shadow" photography demonstrating one of the main properties of discharge-its structure, which is a set of "microexplosion" formations moving against the microwave radiation.
