This type of surface has been employed as backing plane for a bow-tie radiating element in order to synthesize a tunable and steerable antenna. The absorber comprises an array of patches over a grounded dielectric slab, with clear advantage in terms of manufacturability. HIS structures allow achieving absorption by exploiting either dielectric or ohmic (resistive) losses.
