Abstract
In order to deeply explore the plasma stealth performance of hypersonic vehicle, the WKB method is implemented to numerically simulate and analyze the attenuation of the incident electromagnetic wave. Specifically, the relevance between (a) the absorption efficiency and attenuation of the electromagnetic, and (b) the electron density of the plasma, the thickness of the plasma layer, the collision frequency of the plasma and the frequency of the incident electromagnetic wave, under the condition that the electromagnetic wave (in the L, S, C and X bands of the detection radar) is input into the plasma thin plate in a confined space, is systematically studied. The result shows that, in a confined space, the maximum effect of the absorption efficiency and attenuation of electromagnetic can be achieved by an optimal combination of plasma electron density and plasma layer thickness, having guiding significance on development of plasma generator in the confined space and stealth technology of hypersonic vehicle.
