OPTI 6203 - Metamaterials
Metamaterials describes a new field of engineered materials having subwavelength structures, and which have electromagnetic properties not found in nature. Examples include zero and negative index materials which lead to some new applications. Metamaterials are made from “meta-atoms” which are much smaller than the wavelength of the radiation. Meta-atoms are LCR circuits having strong resonant behavior over some chosen bandwidth. The distribution of many such atoms and their mutual interaction determine the bulk metamaterial’s properties. Describing these properties draws from electromagnetics, antenna design, atomic and molecular physics and condensed matter physics. At increasingly small scales (i.e., at the nanoscale), both quantum and plasmonic phenomena can play a role.
