$Temperature‐Controlled Optical Activity and Negative Refractive Index$

Temperature‐Controlled Optical Activity and Negative Refractive Index

Chiral media exhibit optical activity, which manifests itself as differential retardation and attenuation of circularly polarized electromagnetic waves of opposite handedness. This effect can be described by different refractive indices for left‐ and right‐handed waves and yields a negative index in...
