circular polarization cst

As I understand, the circular polarization can be present as superposition of two ortogonal linear polarization with pi/2 phase shifting, but maybe somebody knows, how to define the circular polarized signal on the port directly ?

Thanks.

I suggest to see the examples on the installation directory of MWS; under the directory examples\Transient Analysis\S Parameters\Waveguide Devices there is an Orthomode Trasducer example that is a good reference to solve your doubt.
