Abstract

The problem of electromagnetic pulses propagation in plasma was studied in connection with various problems of radio engineering and radar systems. The description of propagation such signals is based on exactly solvable problems for monochromatic waves. We considered two cases: smooth layer and thin sheet. The conditions for different type of reflection are founded.
