Description
Summary:Plasma stealth is a new concept and principle of stealth technology. Firstly, WKB analysis method is used to analyse the attenuation of electromagnetic wave under the action of plasma. Then, a certain UAV inlet was selected to establish a model, and the inner wall was covered with a ring of closed cavity. Plasma was generated by discharge, and the stealth performance of the inlet was numerically simulated for the L-band electromagnetic wave and its stealth effect was analyzed. This method verifies the feasibility of applying plasma stealth technology to the l-band radar wave for inlet stealth.
