Description
Summary:This paper summarizes recent advances by the authors in the area of metamaterial surfaces (metasurfaces). It covers periodic and non-periodic metasurfaces for near-field electromagnetic manipulation. In addition, the modeling and development of tensor transmission-line metamaterials and tensor impedance surfaces for the realization of planar transformation electromagnetics devices are reported. Finally, preliminary work on metamaterial Huygens' surfaces that can steer, beam shape, and focus electromagnetic waves is outlined. These reflectionless surfaces are based on the Surface Equivalence Principle: a rigorous form of the Huygens' Principle.
