how to calculate power received and port voltages of wire dipoles with 50 ohm load termination. The source is plane wave excitation. I have tried to simulate and in the output, received voltages at loads are zero. Could someone kindly explain. thanks

    Just plot the loads/networks results on a new Cartesian graph in POSTFEKO.
    The image below for a monopole with a load on the wire port and a plane wave over 3 frequencies solved.

    Hi mel, 

    Thanks for your response. I am having problem with meshing. My model produces an error when I do CEM validate.  


    CEM validation

    Error 16232: Isolated (unconnected) segments not allowed. Please mesh the following wire segments finer or ensure correct connectivity:
            Line1.Wire5

     

    Could you kindly comment on it?

    Hi mel,

    I solved it by union of monopole and ground and the meshing problem CEM validate is resolved. Thanks.
