Hi
thanx nhomuathu_hanoi
i have actually gone through that tutorial , but it wast very clear to me that how to prevent higher modes from propagating .... i have give only only integration line , will it do the job?????? can you explain me how does the integration line work?
like ,can a excite a waveport without an integration line?
Also , i have to introduce some dielectric structures , like a cylinder in the middle of the waveguide and study its effect, i think it will excite some higher modes ( the reflections from the dielectric cylinder i mean) ... how can i check if other modes r propagating or not?
I know ,I have too many questions in one post but i would really appreciate if you can help me out!
Thanx
