SPIE Optics + Photonics 2018 - Tunable Hyperbolic Metamaterials for Novel Photonic Devices

Abstract

In this work we present a generalized coupled mode formulation dedicated to waveguides based on double-negative (DNG) as well as single-negative (SNG) metamaterials. Our approach is derived from generalized reciprocity relation, instead of polarization perturbation, which extends its applicability to lossy reciprocal media, including SNG materials. The coupled mode equations are established for various SNG/DNG multi-waveguide configurations and illustrated for two coupled systems based on SNG medium.
