Abstract:
A self-consistent electrodynamic model based on analytic relations, which makes it possible to describe the electromagnetic wave scattering from a thin (compared to the wavelength) plasma channel, is proposed. The results of experimental investigation of the dynamics of the signal scattered by a single channel in air in the pressure range $P_0$ = 10$^4$–1.4 $\times$ 10$^4$ Pa are presented. The results are analyzed in terms of the electrodynamic model.
