A transparent metal structure permits the transmission of light over a tunable range of frequencies, for example, visible light, and shields ultraviolet light and all other electromagnetic waves of lower frequencies, from infrared to microwaves and beyond. The transparent metal structure comprises a stack of alternating layers of a high index material and a low index material, at least one of the materials being a metal. By carefully choosing the thickness of the second material, the transparent window can be tuned over a wide range of frequencies.
Structure métallique transparente qui permet la transmission de la lumière sur une gamme accordable de fréquences, par exemple la lumière visible, et bloque la lumière ultraviolette et toutes les autres ondes électromagnétiques de fréquences inférieures, des infrarouges aux micro-ondes et au-delà. Ladite structure métallique transparente comprend une pile de couches alternées de matière à indice élevé et à indice faible, au moins une de ces matières étant un métal. Le choix soigneux de l'épaisseur de la seconde matière permet d'accorder la fenêtre transparente sur une large gamme de fréquences.
