Inversion of Equivalent Electromagnetic Parameters of Multilayer Absorbing Materials Based on Simulated Annealing Algorithm

Abstract Multilayer gradient absorbing materials are difficult to be modeled and simulated in practical applications. To solve this problem, a method of the inversion equivalent electromagnetic parameters multilayer based on annealing algorithm is proposed paper. The reflectivity material different forms polarization obliquely incident at angles calculated, then used calculate incidence angle single-layer same thickness within combinations find out curve that most similar wide domain material, namely desired parameters. Finally, simulation verification performed. should applied simple, wedged, physically-simulated radar cross-section (RCS), result consistent with application wedged physically RCS. This suggests absorption property calculated material.
