摘要
基于磁场积分方程法(MFIE),对脊波导传输特性进行研究,详细推导出脊波导的截止模式波数、模式电流、模式电磁场、TE和TM模式及衰减系数和特性阻抗等解析表达式,完善了其理论依据,为脊波导在微波通信工程中的应用提供理论基础。最后以双脊波导为例,仿真计算给出了双脊波导(a=2b)中TE 10模式随着s/a和d/b变化的电场等高线示意图。
In this paper,the transmission characteristics of ridge waveguide are studied based on the magnetic field integral equation formulation,analytical expressions are derived in detail for the cut-off mode wavenumber,mode current,mode electromagnetic field,TE and TM modes,attenuation coefficient and characteristic impedance.Its theoretical basis is improved,and a theoretical foundation is provided for the application of ridged waveguides in microwave communication engineering.The simulation calculations are performed to provide a schematic diagram of the electric field contours of the TE 10 mode in the double-ridged waveguide(a=2b)with the changes of s/a and d/b.
