Can anyone explain how we can analytically solve the coupling matrix. Any good calculating tools for solving the coupling matrix, specifically useful for microwave Filters?
There is a lot of good papers on the subject especially by: Cameron or Bell. You can also try to use software that does the job e.g. http://www.gwtsoft.com/
Thank you sir, I already aware about that software as well but i need to analyze the originated method to solve at least we should know how it arises then we can also go to the software as well
