各向异性介质填充矩形波导的FDTD分析
FDTD Method Analysis of Rectangular Waveguide Filled With Anisotropic Medium
摘要
Abstract
This paper describes the difference expression in the waveguide filled with anisotropic medium by using finite-difference time-domain(FDTD)method. In order to demonstrate the validity of the FDTD method, the TE-mode cut-off wavenumbers of the rectangular waveguide filled with lossless electrical anisotropic medium is calculated with the MATLAB tool and a comparison is given. The law of the TE-mode cut-off wavenumbers is obtained when the rectangular waveguide dimension and the loaded width of non-uniaxial electrical anisotropic medium vary.关键词
