Abstract

This paper presents the electromagnetic wave propagation characteristics in plasma and the change of the attenuation coefficients of the microwave with some parameters by using #800mm high temperature shock tube. In order to get the attenuation of the electromagnetic wave through the plasma behind shock wave, the microwave transmission is used to measure the relative change of the wave power. The experimental results reveal that the dependence of the attenuation coefficients on ne, v, w, and L are in good agreement with the theoretical predictions of electromagnetic wave propagations in the uniform infinite plasma when the plasma layer is thick (such as L/λ ≥ 10). We also measure the electromagnetic wave power attenuate value with and without the magnetic field.
