Transmission of electromagnetic waves through a plasma slab produced by a moving ionization source
A study is made of the interaction of electromagnetic waves with a time-varying plasma slab of finite thickness. This slab is produced by a moving ionization source in a gas which is at rest. The static magnetic field excited at the ionization front as the electrons are driven by the incident wave reradiates energy into the electromagnetic wave in the course of the plasma relaxation caused by recombination processes. As a result, an electromagnetic wave of finite amplitude can propagate beyond a time varying slab of an ''opaque'' plasma (..omega../sub p//sup 2/>>..omega../sub inc//sup(/sup 0/)/sup 2/). This result distinguishes this case from the case of a moving steady-state plasma with the same properties.
