Analysis of the Propagation of a Short Radio Pulse in Media with Negative Permittivity

An analysis is carried out in the time domain of the propagation of a short radio pulse through a medium with a negative dielectric constant, which simulates a plasma layer with a given frequency dispersion for a collisionless plasma without taking into account the motion of positive ions. The process of signal formation in the time domain is shown for a plasma frequency of 10 GHz with a radio pulse duration of 0.1 ns with a filling frequency of 10 GHz.It is shown that the plasma layer is a high-pass filter.Examples of the passage of a given radio pulse through a plasma layer for plasma frequencies equal to 5 GHz and 15 GHz are given. For the analysis, we used the method of the impedance analog of the electromagnetic space, implemented in the Tamic Planar Rt-H Analyzer software package. .
