Paper Abstract

Hyperbolic metamaterials can propagate electromagnetic modes with unusually large wave numbers (extraordinary high-momentum modes). The extraordinary high-momentum modes are non-propagating or evanescent modes in common optical media. On the other hand, hyperbolic metamaterials can sustain propagating electromagnetic waves with unusually low wave numbers (extraordinary low-momentum modes). Both extraordinary high- and low-momentum modes are of special interest for a number of applications. For example, the development of these exotic modes, which are fundamental to the operation of hyperlenses, might lead to unprecedented sub-diffraction optical imaging systems. Hyperbolic metamaterials are also of special interest for radiative decay engineering. The inevitable trade-off between optical mode confinement and the optical losses inherent to the metal component is a fundamental challenge for plasmonics and metamaterials. We have carried out numerical analysis of Rytov’s dispersion equations to model loss-compensation in metal-semiconductor hyperbolic metamaterials with extraordinary high- and extraordinary low-momentum modes. Numerical results provide a framework for the design of loss compensation schemes in hyperbolic metamaterials with extraordinary high- and extraordinary low-momentum modes.
