Phase change metamaterial for tunable infrared stealth and camouflage

Optics Express, 2022
In the paper, a type of phase change metamaterial for tunable infrared stealth and camouflage is proposed and numerically studied. The metamaterial combines high temperature resistant metal Mo with phase-changing material GST and can be switched between the infrared “stealthy” and “non-stealthy” states through the phase change process of the GST.

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 ...

Mid-infrared LEDs versus thermal emitters in IR dynamic scene simulation devices [PDF]

, 2006
In a radical departure from conventional thermal emitter-based dynamic IR scene simulation devices, we have tested InAsSbP/InAs LEDs grown by liquid phase epitaxy and tuned at several peak-emitting wavelengths inside the mid-IR band.
