Engineering the Complex-Valued Constitutive Parameters of Metamaterials for Perfect Absorption
Abstract We theoretically studied how to directly engineer the constitutive parameters of metamaterials for perfect absorbers of electromagnetic waves. As an example, we numerically investigated the necessary refractive index n and extinction coefficient k and the relative permittivity ε and permeab...
