| Abstract: | By using finite element method combined with absorbing boundary conditions, the numerical calculation of stealth properties of structural radar absorption materials (SRAMs) is studied. Based on the layer and combination program, radar cross-section (RCS) of 2D two-and three-layered SRAM structures is calculated to a chieve an optimal combination design of stealth properties. Finally, the influence of angle change between ripple and bottom board of rippled SRAM structure on RCS is analyzed and a positive tendency is obtained. |
