Radiophysics and Quantum Electronics Aims and scope

Abstract

Based on a numerical solution of the nonlinear Helmholtz equation, we consider the increasedpower radiation through a layer of plasma from a slot antennas excited by an H-wave. The cases of positive (∂ε/∂|E|>0) and negative (∂ε/∂|E|<0) nonlinearities are analyzed. The effect of restriction of the transmitted power is investigated for negative nonlinearity and the formation of the self-supported waveguide channel is considered for positive nonlinearity. The existence of bistability with variation in the feeding power is shown. The plasma structure near the antenna is analyzed for the high level of the radiated power.
