Analysis of the Transmission Property of Ridge Waveguide with Operator Theory
用电磁场算子理论分析脊波导的传输特性

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.
