摘要
给出了用时域有限差分(FDTD)法分析各向异性介质填充波导问题的差分格式,实例计算了各向异性介质填充屏蔽微带线的传输特性,分析了影响特性参数的因素及其变化趋势.
This paper presents a difference expression of waveguide filled with anisotropic medium by using finite - difference time - domain （FDTD） method. In order to demonstrate the validity of the method, the microstrip line filled with anisotropic medium is calculated and a comparison is given. The law, the relation of the normalized cut - off wavenumber and the loaded medi- um width in microstrip partially filled with anisotropic medium have been given.
