Iam designing a mode selector using HFSS. Actually i need to characterize three modes. TE01, TE02, TE03. In that i just have to select TE03 and give it to wave guides. So, can any one suggest how to design this. I have already some theoretical calculations by which i can achieve this by a circular wave guide consisting of array of holes with 120 degree between each array and by placing different distances between two consecutive holes of an array. Can anyone give me some suggestions about my design??
The input frequency of my design is 42GHz, and i want coupling factor of -40dB.
