[MOVED] Waveguide Termination

hello every one,I`m designing a rotman lens with waveguides as ports in CST. for port absorbers,I have to terminated the waveguides with an absorber. I don`t want to use a wedge or complicated designs and also I don`t want to use waveguid ports as absorbers. what can I do in CST?

It is difficult to advise you as you do not want to follow good advices. Then nothing is left, sorry.

but my prof says i cant use the wedge for simulation,in practice yes but simulation no. I have no fault.
