Abstract
Auxiliary differential equation finite-difference time domain (ADE-FDTD) expressions of drude dispersive medium model are applied to simulate stealth characteristics of metamaterials coating. Then, simulated annealing algorithm is used to optimize electromagnetic parameters considered include metamaterials coating, collision frequency drude frequency and coating thickness. The results show that monostatic RCS of metal cylinder covering with metamaterial coating can reduce 6.3dB and bistatic RCS of metal cylinder covering with metamaterial coating can shrink 0.1dB less than before. Simulated annealing algorithm can play an important effect on stealth characteristics of metamaterials.
