Microwave Engineering Projects

Hello mates,
I was actually trying to find a project based on Microwave engineering as a part of my course work. And I have no clue where I could find one. I actually worked on project titled "Microwave Cavities with various loads" which involved the HFSS ansoft software to simulate and get the results. So I wonder if anyone could suggest me any project related to the one I did or some resource which could help me out.

Thank you,
