Paper Abstract

A multilayer metal-insulator (MMI) stack system is viewed as an anisotropic metamaterial to exhibit plasmonic behavior and a candidate of "metametal". The dispersion of the fundamental super mode propagating along the boundary between an MMI stack and a dielectric coating is theoretically studied and compared to that of surface waves on a single metalinsulator boundary. The conditions to obtain artificial surface plasmon frequency are thoroughly investigated, and the tuning of effective surface plasmon frequency is verified by electromagnetic modeling. The design rules would bring important insights into layer-by-layer metamaterial development related to superlenses, optical lithography, nanosensing and imaging.
