We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

a的平方的值没有考虑模式功率本身不同问题,需要看链接中最后的解释。/forum/forums/topic/ansys-insight-%e5%85%b3%e4%ba%8emode-expansion%e7%9b%91%e8%a7%86%e5%99%a8%e7%9a%84%e4%bd%bf%e7%94%a8%e5%92%8c%e7%bb%93%e6%9e%9c%e5%88%86%e6%9e%90/#post-286053

按理Tforward 应该与abs(S)平方一样,但是如果它们位于不同位置可能有少许差别。此时应该以Port结果为准吧。
