摘要: 本文首先建立了干板状有耗双各向异性波导的模型,并将其传输模的横向场分量用纵向场分量来表示。用数值方法分析了高阶混合模的模分裂和场分布特性,并且考察了介质的各向异性和损耗程度对混合模的影响。Abstract: The transmission characteristics of high-order hybrid modes in a bianisotropic loss slab bounded by perfectly conducting planes are investigated, and in such complex waveguides, the transverse field components are also expressed in terms of the longitudinal field components of hybrid modes. Numerical results are presented to demonstrate the effects of anisotropy, lossness and different constitutive parameters on the dispersion and field-distribution behavious, and it is suggested that bianisotropic materials have potential applications for the microwave and millimeter wave regimes.
