Toward the Nonstationary Theory of a Telecommunication Channel Through a Plasma Sheath

Abstract

We present an analysis of dynamic processes for the electromagnetic wave packet passing through the opaque media with quasi-free charges. We consider plasma sheath surrounding the spacecraft as it passes through the dense layers of the atmosphere. In order to provide effective tunneling of the signal to the receiving antenna, the dielectric “resonator” between the surface of the vehicle and plasma is supposed. We discuss the peculiarities of such radio frequency telecommunication channel and analyze in detail tunneling of the wave packet to the resonator and the decay processes for excited oscillations in the resonator. The peculiarities of tunneling through the nonstationary plasma layer are analyzed.
