Transmission Characteristics of Asymmetric Ridge Waveguides [Issue, 中] / Sun Hai // Radar Science and Technology. -2006, 4 (4). -240-244 (D) Propose the finite difference method to analyze the transmission characteristics of the cutoff wavelength and the field structure diagram of the asymmetric ridge waveguide main mode. The formula to calculate the related parameters by finite difference method is deduced. The cutoff wavelength of the main mode ridge waveguide can vary with the position of the ridge. In this paper, the variation of the cutoff wavelength and the field structure of asymmetric ridge waveguide and L-shaped waveguide ridge are calculated and the calculation data and the graph are given. The calculated results are in good agreement with the relevant literature, which proves that the calculation method and calculation results presented in this paper are correct and feasible.
