摘要
In order to synthesize the multi-layer radar absorbing materials (RAM) with a thin thickness and wide bandwidth, accelerating genetic algorithm (GA) with constraints and elitist strategy is employed to design the multi-layer RAM satisfied by a special value of reflection loss to electromagnetic wave. Given predefined available materials with frequency-dependent permittivity and permeability, the GA technique determines the optimal material choice for each layer and its thickness. The algorithm was successfully applied to the synthesis of double-layer to four-layers RAM coatings in the frequency range of 2-18GHz, and the optimization results was evaluated.
