Abstract
The present invention relates to a far-to-mid-infrared absorptive optical coating, including: an optically opaque conductive substrate; a primer layer applied to a surface of the optically opaque conductive substrate; a conductively loaded dielectric media which coats the optically opaque conductive substrate on the primer layer; and a monolayer of a randomly deposited microspheres or microbubbles, each of the microspheres or microbubbles having an outer surface; and a monolayer of a metal film deposited on the outer surface of each of the microspheres or microbubbles by an atomic layer deposition (ALD) process to form a coated absorptive surface on the microspheres or microbubbles; wherein the monolayer of coated microspheres or microbubbles is applied to the conductively loaded dielectric media and cured to result in the far-to-mid infrared absorptive optical coating which provides wavelength-scale absorptive-scatters and in-band impedance matching at a surface of the monolayer of the coated microspheres or microbubbles.
