| Abstract: | The transmission characteristics of asymmetrical double-ridge waveguide have been analyzed by the finite difference method.The cutoff wavelength,single-mode bandwidth and field pattern of the asymmetrical double-ridge waveguides have been presented,and they have also been compared with those of the symmetry double-ridge waveguides.The asymmetrical double-ridge waveguide can realize miniaturized waveguides,and this significant important in microwave engineering.The design data have been considered to be accurate enough and helpful in practical application. |

| Keywords: | finite difference asymmetrical double-ridge waveguide cutoff wavelength single-mode bandwidth field pattern |
