Resistive Cards Modeling in CST

[tuli]

Hello,

I am trying to analyze in CST a waveguide assembly which includes a resistive card made of a material which has a resistivity of 150 ohm/square.
The card ascts as a mode supressor.
How do I define the material properties?

Any suggestion would be appreciated.

Thanks

I don't use CST, but I do use ANSOFT HFSS. Couldn't you just assign an impedance to the surface of the resistive card? In HFSS, you just pick the surface and assign the impedance in ohms/square.
