Meta-material behaviour of the new Coherently Radiating Periodic Structures (CORPS)

In this paper, the study of the new Coherently Radiating Periodic Structures (CORPS) like a Metamaterial sets out. The shape of the structure under study is composed by two different layers, one layer is an array of square metallic patches and the other layer is an array of cross shaped slots. All the elements of each layer are placed in a rectangular lattice grid of lg, ensuring coherent coupling between elements of the same layer being this the main feature of the Coherently Radiating Periodic Structures (CORPS). To built up the whole structure, a total number of three layers (patches-slots-patches) are stacked and separated by dielectric slabs of either 10.2 or 1.0006 (air) of permittivity. The simulations were done using MoM and Finite Elements Method (i.e. Ansoft Designer and HFSS respectively).
