Reply To: Transmission values are very low during s parameter extraction

Sorry about that. Thanks. In the s parameter extraction in FDTD, i got a warning that my device lacks reciprocity . The FDTD simulation runs fine without any divergernce warning and any other error . The simulation is broadband. What will be the reason for that? I excited all ports during simulation. My device is a 4 X 4 mmi with subwavelength gratings.
