Antennas in Compressible Plasmas,
Abstract
Measurements of antenna impedance are frequently used to determine the properties of plasmas which occur in the ionosphere and during the atmospheric reentry of space vehicles. An accurate understanding of the performance of antennas in plasmas is required for these purposes as well as for determining ways to minimize the reentry communications blackout problem. The results of the ionospheric rocket experiments have indicated the necessity, when analyzing antenna performance, of using a 'warm' or 'compressible' plasma theory which takes into account the thermal motion of the plasma particles. The classical derivation of the hydrodynamic, compressible plasma theory equations is included in this report together with a discussion of appropriate boundary conditions. A review of the antenna analyses which have been performed using this compressible plasma theory is presented to illustrate the present 'state of the art' of antenna-plasma analysis. (Author)
