Dyakonov-Tamm waves guided jointly by an ordinary, isotropic, homogeneous, dielectric material and a hyperbolic, dielectric, structurally chiral material

摘要

The planar interface of an ordinary, isotropic, homogeneous, dielectricmaterial and a hyperbolic, dielectric, structurally chiral material can supportthe propagation of one or multiple Dyakonov-Tamm waves, at a specifiedfrequency and along a specified direction in the interface plane. When multipleDyakonov-Tamm waves can exist, they differ in phase speed, propagation length,degree of localization to the interface, and spatial profiles of the associatedelectromagnetic fields. Dependence on the relative permittivity scalar of theisotropic partnering material suggests exploitation for optical sensing ofanalytes.
