Thanks.

    Hi SSachdeva

     

    The message indicates that you are exciting (or trying to receive at the 2nd port) the waveguide at a frequency where there is no propagating waveguide mode.

    Are you perhaps simulating over a too wide frequency range? Then your start frequency should be set just above the cut-off frequency
