## PASSAGE OF AN ELECTROMAGNETIC PULSE THROUGH A LAYER OF HOMOGENEOUS PLASMA (EXACT SOLUTION)

A. A. Khrushchinskii and D. Yu. Churmakov UDC 533.9.08,533.9.01,533.951 The authors found an exact analytical solution of the problems on reflected and transmitted waves in interaction of a short electromagnetic pulse with a plasma layer of finite extension. The problem is solved assuming the linearity of material equations. Analytical expressions of Green functions are obtained for the corresponding problems that allow one to write solutions for the transmitted and reflected waves with any shape of an incident wave. The exact solutions depend substantially on the plasma density and layer extension, which makes it possible to use them in processing experimental results for extraction of the above-mentioned parameters.
