Spectro-polarimetric imaging in the long-wave infrared (LWIR) region plays a crucial role in applications from night vision and machine perception to trace gas sensing and thermography. However, the current generation of spectro-polarimetric LWIR imagers suffers from limitations in size, spectral...

Manufacturers frequently use coatings to protect the structural stability of engines or power generators operating at high temperatures. Ceramic shields, however, have not been able to adequately address a critical, performance-limiting factor: heat radiation. Researchers have engineered ceramic...

Metamaterials operating at frequency ranges in which the dielectric permittivity is close to zero have been discussed for use across a wide range of optical applications. Sean Molesky and colleagues from the University of Alberta in Canada, have now proposed methods for engineering thermally excited...
