ELECTROMAGNETIC CAVITY ABLE TO SUPPORT TAMM MODES

摘要

An electromagnetic cavity (10, 20, 30, 40, 60) able to support Tamm modes and possessing a resonant frequency in the THz domain, comprising: - an interference mirror that is reflective in the THz domain, this mirror consisting of a stack (7) of dielectric layers comprising an alternation, in a z-direction, of two different layers, a layer (2) called the high-refractive-index layer and a layer (4) called the low-refractive-index layer, the index of the low-refractive-index layer being lower than that of the high-refractive-index layer, and being manufactured by mechanically stacking layers or by joining dielectric layers to one another. - an upper metal layer (5) deposited on or added to an upper dielectric layer of said interference mirror so as to form a structure that supports at least one Tamm mode in the THz domain, the upper metal layer (5) being structured so as to form an antenna possessing a resonant frequency equal to that of the electromagnetic cavity.
