Properties and Applications of Lossy Metamaterials

Abstract

The complex permittivity ( ) and permeability ( ) of a material determines the response of the material to electromagnetic radiation. In many cases, the real part of and are both positive for materials that can be found in nature. Metamaterials (MTMs) are engineered media that are designed to have either a negative permittivity or a negative permeability or both. Negative permittivity and permeability cause electromagnetic waves travelling through this medium to exhibit unusual characteristics.
