The Absorbing Characteristics of plasma-filled double-layer Jaumann screen

Jaumann screen, developed from Salisbury screen, is a typical absorbing structure, but its absorbing characteristics are fixed. In this paper, a double-layer Jaumann screen filled with plasma is proposed, and its absorbing characteristics are simulated and analyzed. Through simulation and analysis, the absorbing frequency of double-layer Jaumann screen filled with plasma can be adjusted by adjusting the parameters of plasma, and its absorbing frequency bandwidth is wider than that of traditional double-layer Jaumann screen.
