THEORETICAL AND EXPERIMENTAL STUDIES OF 35 GHZ AND 96 GHZ ELECTROMAGNETIC WAVE PROPAGATION IN PLASMA

Abstract

The 35GHz and 96GHz electromagnetic wave propaga- tion characteristics in plasma are studied theoretically and experimen- tally in this paper. The variations of the electromagnetic wave at- tenuation along with the plasma density, plasma collision frequency and electromagnetic wave frequency are acquired based on the physi- cal model. The electromagnetic wave propagation properties in plasma are studied experimentally with the shock tube, and the experimental results match well with the theoretical ones. Both the theoretical and experimental results indicate that increasing the electromagnetic wave frequency is an alternative and efiective method to solve the reentry blackout problem.
