Penetration of microwave with a stochastic jumping phase (MSJP) into overdense plasmas and electron collisionless heating by it

Abstract

The results from a theoretical study as well as from numerical simulation of either direct or inclined incident to boundary vacuum-overcritical density plasma of the linearly polarized electromagnetic waves are discussed. The chief results of our studies are the following: (i) at considered parameters the penetration coefficient (PC) of the MSJP is about one order of magnitude higher than a PC of the wide-band regular electromagnetic wave (WREW); (ii) in particular, at inclined incident of the MSJP a electron heating is most essential and besides the electron distribution function has high energy “tail”. This anomalous behavior of a penetration coefficient as well as the electron heating are connected with a jumping phase of MSJP.
