摘要
该文用电磁场算子理论通过多个虚拟边界的电场和磁场的耦合求解脊波导的本征值,在此基础上讨论了脊波导的的传输特性。所采用的并矢格林函数没有奇异项,可以化为标量格林函数来表示,而且能很方便地计算,并与经典方法计算的结果进行了比较。
The eigenvalues of ridge waveguide are solved with the matching of electric and magnetic field on the multiple virtual boundaries by partial differential operator theory and the property of ridge waveguide is discussed. The dyadic Green's function has no singularity and can be transformed into scalar Green's function. The results computed by partial differential operator theory are compared with those computed by equivalent transmission line method.
