摘要
利用时域有限差分法分析了标准矩形波导内的各种不连续结构。采用理想匹配层边界条件以有效吸收边界面上的出射波,并与色散边界条件的吸收效果作比较。然后。
Various discontinuities inside standard rectangular waveguide are analyzed using finitedifference timedomain method (FDTD). The perfectly matched layer(PML) boundary condition is used to effectively absorb out going wave on the boundary plane by comparison with the absorbing performance of dispersive boundary condition. Then coefficients of its equivalent twoport networks of various kinds of discontinuities inside waveguide are given under main mode operation.
