hi guys,
I am using cst to simulate metamaterial sturctures. One problem confuses me a lot : I oftern got results of s11 and s12, which do not satisfy law of energy conservation, since s11^2+ s12^2 >1, even in the case of lossy metal structure. I thought something is wrong with my simulation . To my surprise, many cst official modals also generate s parameters like that way!
Will it affect extracting epsilon and mu correctly? Do you guys meet such problem?
thanks
