Perfectly-Matched Metamaterials
Abstract
The proposed research effort will theoretically and numerically explore perfectly-matched metamaterials in two and three dimensions, as well as pursue their practical realization. Perfectly-matched metamaterials are anisotropic, inhomogeneous metamaterials whose constitutive unit cells possess the unique property of being impedance matched to each other, as well as to the surrounding space under all possible excitations. As a result, the metamaterial s performance does not rely on inter-cell or bulk reflections to perform a prescribed electromagnetic function. Instead, it relies on refractive effects and path length, and therefore promises true time-delay performance and broadband operation. In contrast to dissipative (lossy) perfectly-matched layers (PMLs), that are commonly used to terminate computational domains in numerical electromagnetic solvers, the proposed metamaterials are lossless
