摘要: 本文首先建立了干板狀有耗雙各向異性波導(dǎo)的模型,并將其傳輸模的橫向場分量用縱向場分量來表示。用數(shù)值方法分析了高階混合模的模分裂和場分布特性,并且考察了介質(zhì)的各向異性和損耗程度對混合模的影響。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.
