I have a request to introduce a new feature called “Power Wave probe”. For example, when we do AC simulation, we can use Voltage probe and Current probe. When we do S-parameter simulation, then there is no way for us to measure power waves (a and b). I am attaching two PDF files that explain this idea better.
About 2 year ago, I contacted Michael Margraf with this question. He said it was an interesting idea and that he would look into it. Well, so far it hasn’t happened.
