Here we investigate theoretically and numerically the coupling between surface plasmon
polaritons (SPPs) in monolayer graphene sheet arrays that have a period much smaller than …

Inside of a hyperbolic medium, the principal components of the permittivity tensor have
opposite signs causing the medium to exhibit a 'metallicbr'type of response to light wave sin …

Hyperbolic media exhibit unparalleld properties, eg, as light absorbers in photovoltaics and
photonics, as superlenses in far-field imaging, as subwavelength light concentrators in …

Although counter-intuitive features have been observed in non-Hermitian optical systems
based on micrometre-sized cavities, the achievement of a simplified but unambiguous …
