cst absorber adaboard

Hi,
is it possible simulate perfect absorber in CST MWS ? How ? Thank you very much...

it is supposed to be possible. i remember there was a paper on perfect absorber published in PRL 2008, which is based on the simulation using CST MWS.

Thank,
OK, so it is possible, it is good message, so second question is, HOW ? :D
and btw, can you tell me, what is PRL 2008 ? :)

You can use the preloaded absorbers from Eccosorb in CST or if you wish then define a material and make tan delta very high.

Thank, yes I know. But I need perfect absorber without "return energy" = matching. I tried very high tan delta, but it was not be good.....

Try define the face as port. The port is matched automatical.

Yes I know, but port you can not form, it is only rectangle..... and it is not my case.
Thank
