| description | This document is a disclosure of two related classes of metamaterial elements, based on a set of planar geometries that are homeomorphic to a coaxial element, or a sphere together with a torus. These cavities support a set of lossy optical resonances, known as quasinormal modes. Depending on the surrounding materials and the choice of quasinormal mode, the optical elements can be used either in transmission or reflection mode, and to generate either effective electric or magnetic dipoles. The metamaterial element is defined as a cavity with coaxial topology to operate in a particular range of quasinormal modes, defined by the mode numbers, within an operating bandwidth. The elements are tuned by application of a voltage differential to liquid crystal placed in the interior of the cavity of each respective element. |
