| Abstract: | The rectangular waveguide filled with non-symmetrical dielectric is analyzed by using a new Fourier's expansion-differential method for analyzing groove guide with arbitrary shape,and the correctness of the new method is verified.In addition,a new type of waveguide filled with periodic homogeneous dielectric waveguide is analyzed.The new method has the advantages of simple and easily feasible computation to solve the engineering problem in microwave and millimeter wave's application.So it is of available for analysis of other waveguides filled with non-homogeneous dielectric |
