将过模矩形波导中应用的裂缝式滤模器看作为具有周期不均匀性的过模波导,由网络分析法研究了它的传输特性。在单元不均匀性很小的假定下,用微扰法求得其解。
The crack filter used in over-mode rectangular waveguide is considered as an over-mode waveguide with periodic inhomogeneity, and its transmission characteristics are studied by network analysis. Under the assumption of small unit inhomogeneity, the solution is found by perturbation method.
