Visible-infrared compatible stealth metamaterial for space applications

Optics Express
Space-to-ground visible and infrared stealth is of great importance in space technology. In this paper, we propose and demonstrate a visible-infrared compatible stealth metamaterial for space applications. The metamaterial combines a multilayer of Ge and Mo with a periodical array of Ge nano-pyramids on the top.

Transparent transmission-selective radar-infrared bi-stealth structure

Optics Express, 2018
We report a multifunctional metamaterial composite structure that not only provides the broadband radar and thermal infrared bi-stealth function but also possesses an in-band microwave transmission window and high optical transparency. It is composed of four metasurface layers made of indium tin oxide (ITO) films with different surface resistances ...
