剩余反射对滤光片纹波的影响

Effect s of residual reflection on the ripple of filter

通过对一段均匀直波导的计算，验证该算法比使用一阶吸收边界条件的时域有限元法，虚假剩余反射回波平均要低10dB以上，达到了工程计算的要求。

The more lower fictitious return wave loss , which is lower – 10 dB than the one yielded from the first order absorbing boundary condition , is illustrated in our method .
