[运算]CST MWS多导体设置差模与共模问题

如题设置差模与共模的时候出现警告：The multipin potential settings on port 1 result in linearly dependent field patterns. Please note that the mode fields will be orthogonalized to ensure stability.还有在获得S参数的前面部分，它的回波损耗参数居然一部分为正，请问有谁遇到过这 .. tIV9Y=ckr0

The multipin potential settings on port "xxx" result in linearly dependent field patterns. Please note that the mode fields will be orthogonalized to ensure stability. IY!8j$'|

The defined potential sets should result in linear independent field patterns, e.g. the ”even” and ”odd” modes in a three conductor port. Otherwise the fields at the port cannot properly be decomposed into mode amplitudes. Please check whether the potential set definition is meaningful or consider treating the port as single-ended.

楼主要注意学术词汇的严谨性。按照回波损耗的定义，无源系统的回波损耗就应该是正值。 T^$`

说白了，楼主问了两个算命贴。

不好意思哈！新手小白，我想说的就是S11参数。它一部分为正数，在计算TDR的时候就发生了有负数的情况

那个文件太大了，我看能直接发给你不
