Negative-index metamaterial

ID: negative-index-metamaterial

Negative-index metamaterials (NIMs) are artificial materials engineered to have one or more negative values of effective material properties, such as permittivity (ε) and permeability (μ). These materials exhibit unusual electromagnetic properties that are not found in natural materials. The most significant characteristic of NIMs is that they can bend electromagnetic waves in the opposite direction to what is observed in conventional materials.
