Hi all;
Can anyone tell me that of How much number of TE and TM modes should be enough? for simulating a periodic surface (Frequency selective surface) in hfss. Mean to say if i keep 10 modes both TE and TM the resulting S21 value is -60dB at 4 GHz frequency so if i increase the number modes to 14 then the convergence issue is faced enev i increased the number of passes. Kindly tell me the difference what would happen if use 10 modes or 14 modes in mode calculator in floquet port in HFSS. :?:
