Abstract :
Resonant magnetic properties of recently introduced high-impedance surfaces are studied using analytical modelling and numerical simulations (HFSS and IE3D packages). It is found that the new structure can be effectively described as a layer of an artificial magnetic medium (AMM) in two different situations: plane wave reflection and loading of patch antennas. A rather wide frequency band of resonant effective permeability has been demonstrated in both theory and simulations. The resonant band is especially wide when the structure (considered as an AMM) interacts with the field of a patch antenna
