Paper Abstract

A metamaterial designed to have simultaneous negative permittivity and permeability may be built from a cubic lattice of spheres and a three dimensional wire grid embedded in a host medium. Based on reported theory, the spheres must have higher permittivity than the surrounding medium and be smaller than the wavelength of the electromagnetic radiation in the host medium. Metamaterials based on embedded spheres are expected to be isotropic. This paper presents simulated and effective medium theory reflection and transmission parameters of a plane parallel structure of this new metamaterial. The predicted behavior exhibits a pass band structure where the permittivity and permeability are simultaneously negative.
