Manipulating surface plasmon polaritons with nanostructured TCO metamaterials

Abstract

We propose and implement a new concept for three-layered transparent conducting oxides (TCO) based nanostructured metamaterial. It is based on alternating AZO, GZO and PbS layers. In particular, we propose a novel metamaterial for surface plasmon polariton guiding. Specific example of AZO/GZO/PbS metamaterial and its dispersion engineering are studied in details. The general original concept of metamaterials based on inclusions of the additional layers is discussed.
