Summary:
A rigorous full-wave cavity model is developed for 2D vialess (i.e. uni-planar) metallic periodic structures, which may or may not have a PEC ground plane. This model considers all the homogeneous material blocks in these structures as coupled electromagnetic cavities. This coupled cavity problem is then solved using magnetic vector potential. The via-less artificial magnetic conductor (AMC) surfaces are analyzed using this cavity model and the wave reflection coefficients are calculated for normal incidence case. The results show good agreement with the full-wave HFSS simulation results. To confirm the accuracy of this method, we also compare the electric fields calculated using the cavity model and HFSS.
