Metamaterials and Their Applications Sherman W. Marcus, Chaim Schwartz, Menachem Naor MANOR Division, RAFAEL, Haifa, Israel Abstract — The macroscopic behavior of materials in an EM field is determined by their values of permittivity εr and permeability μr relative to free space which are generally greater than unity. For specially engineered "metamaterials", it has been found possible to obtain other effective values for εr and μr. Rafael has developed basic phenomenological models for simulating refraction, scattering and transmission effects of metamaterials in a plane wave and/or point source environment. These tools are building blocks for such metamaterial applications as lenses and cloaks, and include hardware design, ray tracing, full wave solutions, scattering and cloaking. Index Terms — Metamaterials, propagation, lenses, cloaks, ray tracing. I. INTRODUCTION The macroscopic behavior of materials that are subjected to electromagnetic waves is determined by their constitutive parameters: permittivity ε and permeability μ. The values εr, μr of these parameters relative to their free space values are generally ≥1. It has been found possible, however, to "engineer" materials for which εr
