SOME CALCULATIONS OF THE PHASE SHIFT AND ATTENUATION RATES OF THE HYPERSONIC PLASMA SHEATH
Abstract
Electromagnetic parameters (relative permittivity, relative conductivity, ordinary index of refraction, extinction or absorption coefficient, attenuation rate, phase coefficient, reflection coefficient for the electric field) of the plasma sheath surrounding hypersonic vehicles are evaluated for plane-wave propagation using small signal macroscopic approximations. The parameters are computed at typical telemetering frequencies from 250 mc to 30,000 mc. The results are plotted as functions of the altitude and speed of the vehicle. Parameters for longitudinal propagation of transverse electromagnetic waves in a magneto-plasma are also computed. (Author)
