I m trying to model a waveguide transition from rectangular to cylindrical waveguide for a radiation problem. I tried in 2 ways:
(1) lofting between both solid waveguides & then opted "shell" operation but that did'nt work.
(2) lofting between already hollow both waveguides but that also did'nt work.
Pls suggest how to model a rect to cir waveguide transition in cst.
