摘　　要：均匀平板传输线中的不连续性等效电容已经有了比较满意的求法.由此所得的电容值可应用于均匀脊波导的截止波长的计算.本文考虑含有两种不同介质的脊波导的情况,求得截止和导波状态下横向等效电路中的不连续性等效电容.并由横向谐振法推出这种不均匀情况下脊波导的截止波长和色散关系.The problem of the equivalent capacitance of discontinuty in parallel transmis- sion line has been solved with satisfaction.The value of this capacitance can be used to calcu- late the cutoff wavelength of homogeneous ridge waveguide.In this paper,the ridge waveguide which contain two kinds of media is considered,caculating the equivalent capacitance in the cutoff and the guiding wave state.Then the transversal resonance method is applied to deduce the cutoff wavelength and the dispersion of this inhomogeneous ridge waveguide.
