Experimental studies of electromagnetic wave propagation in a plasma
Abstract
The results of a simulation test of microwave propagation characteristics carried out in the psi 800 mm shock tube are reported. The experimental technique and working principle are presented. The results show that when the plasma layer is thick, correlations between the attenuation coefficients of the electromagnetic waves determined from the measurements and the parameters n(e), num, omega, and Z are in good agreement with theoretical predictions of electromagnetic wave propagations in the uniform infinite plasma. When the plasma layer is thin, the ordinary theoretical results are only in qualitative agreement with the experimental observations in the present parameter range, but the formula for the electromagnetic wave propagation theory in the uniform infinite plasma cannot be used for quantitative computation of correlations between the attenuation coefficients and the parameters n(e), nu, omega, and Z.
