人工磁导体结构组成间隙波导的理论仿真研究

摘要

The dispersion equation of periodic parallel metal wire is studied. The equivalent circuit diagram of PEC-AMC structure is given. The propagation mode of electromagnetic wave in PEC-AMC structure is analyzed, and the dispersion curve of the structure is obtained. According to the theory, two methods(CST /HFSS) are used to design the gap waveguide working in 1. 2-2. 2GHz. The comparison of the two results shows the feasibility for Gap Waveguide composed of Artificial Magnetic Conductor.%介绍了周期平行金属线的色散方程,给出了PEC-AMC 结构的等效电路图,分析了PEC-AMC 结构中的电磁波传播模式,得出了该结构的色散曲线.根据理论用CST 和HFSS 两种仿真软件设计了工作在1. 2-2. 2GHz 的间隙波导,将两种结果进行了对比,证明了由人工磁导体结构组成间隙波导的可行性.
