ON THE NATURE OF RESONANCE PHENOMENA IN RADIO-WAVE SCATTERING ON METEOR-TRAIL MODELS (O PRIRODE REZONANSNYKH YAVLENII PRI RASSEYANII RADIOVOLN NA MODELYAKH METEORNYKH SLEDOV),
Abstract
Theories on the nature of plasma resonance are reviewed on the basis of experimental data on resonance scattering of radio waves by models of meteor trails. Experiments were conducted at lambda = 8-13 m with a cylindrical gas-discharge tube (inside diameter, 1.02 cm; length, 70 cm) containing mercury vapor. During the transverse polarization of an incident wave with variations in the discharge current, a series of reflected signal maxima, believed to be caused by resonance phenomena was observed. Fundamental and higher resonance modes were observed, which behaved similarly under various conditions of scattering. Theories based on models of cold plasma could not be confirmed experimentally. Higher resonance modes are attributed to the motion of hot electrons. This phenomenon indicates an interaction between the electric field of the incident radiation and plasma waves. (Author)
