Hi, I am simulating an antenna backed by an AMC (artificial magnetic conductor) array in HFSS. At simulation completion, I am unable to get any plot for S11 (S parameters) however the gain plot, and radiation plot is ok. The simulation doesn't show any error. Please have a look at the picture. Thanks.
