  • Electromagnetic cavity able to support Tamm modes
    Patent number: 12181694
    Abstract: A Tamm electromagnetic cavity (10, 20, 30, 40, 60) 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 of dielectric layers (7) comprising an alternation, in a z-direction, of two different layers, a layer referred to as the layer of high refractive index (2) and a layer referred to as the layer of low refractive index (4), the index of the layer of low refraction being lower than that of the layer of high refractive index, and being manufactured by stacking layers mechanically 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.
