Abstract :
The cutoff frequency of heteromorphic waveguide in special structure is solved with dyadic green function method and the matching of electric and magnetic field on the invented boundary by partial differential operator theory. The method may be used to solving the cutoff frequency of almost all of the modes precisely and expediently. The method may also be used to calculating the propagation characteristics of ridged waveguide and other heteromorphic waveguide loaded rectangular metal
