摘　　要：推导得出条形和片形金属周期结构的传输线电路模型。根据电路模型与金属条周期复合材料结构,利用C语言建立对应结构的迭代算法和算法模块包;利用所建立的算法模块包、Traits GUI库、Matplotlib库和Python脚本语言完成数值仿真。仿真结果与商用软件HFSS仿真结果高度吻合,电路模型可以很好地描述周期结构透射谱的物理机制,提供了很好的数值仿真手段。阻性毯面层的加入提高了材料的吸波性能。The transmission line circuit model of strip and sheet metal periodic absorber structures were de rived. According to the circuit model and the metal periodic composite structures, the iterative algorithm and model package by C language were programmed. The numerical simulation was finished with using the compiled C package, Traits GUI package, Matplotlib package and Python language. The result was agreed with the simulation results of commercial HFSS software. The circuit model can straightly describe the physical mechanism of the transmission spectrum for the periodic absorber structure,and provide a useful numerical method. Resistive sheet improves the ab-sorber performance of material.
