Title (EN) LOW-LOSS IR DIELECTRIC MATERIAL SYSTEM FOR BROADBAND MULTIPLE-RANGE OMNIDIRECTIONAL REFLECTIVITY
(FR) SYSTEME EN MATERIAU DIELECTRIQUE A FAIBLE PERTE D'INFRAROUGE POUR LA REFLECTIVITE OMNIDIRECTIONNELLE A PORTEES MULTIPLES DE BANDE LARGE
Abstract: front page image
(EN)A multiple-range omnidirectional reflector (2) includes a plurality of bilayers (4). Each of the bilayers includes a first layer (8) comprising of a low absorption and low refractive index material and a second layer (10) comprising of a high refractive index and low absorption material. Varying the thickness (h1,h2) of one or more of the bilayers (4) produces multiple omnidirectional reflecting ranges.
(FR)La présente invention concerne un réflecteur omnidirectionnel à portées multiples (2) comportant une pluralité de bicouches (4). Chacune des bicouches comprend une première couche (8) incluant un matériau à faible absorption et à faible indice de réfraction et une deuxième couche (10) incluant un matériau à indice de réfraction élevé et à faible absorption. En faisant varier l'épaisseur (h1, h2) d'une ou des bicouches (4), on produit des portées de réflexion omnidirectionnelles multiples.
