NEW ANTENNA TECH TO EQUIP CERAMIC COATINGS WITH HEAT RADIATION CONTROL

Page
The gas turbines powering aircraft engines rely on ceramic coatings that ensure structural stability at high temperatures. But these coatings don’t control heat radiation, limiting the performance of the engine. Researchers at Purdue University have engineered ceramic “nanotubes” that behave as...

Single Photon Driven Quantum Phase Transition

Page
The temporal dynamics of large quantum systems perturbed weakly by a single excitation can give rise to unique phenomena at the quantum phase boundaries. Here, we develop a time-dependent model to study the temporal dynamics of a single photon interacting with a defect within a large system of...

Latest paper in Nature

News: July 26, 2023
Our recent work on 'Heat-assisted detection and ranging' has been published in Nature. We discuss how Machine perception uses advanced sensors to collect information about the surrounding scene for situational awareness . State-of-the-art machine perception using active sonar, radar and LiDAR to...

TeX Vision

Page
The resolution of optical imaging is limited by diffraction as well as detector noise. However, thermal imaging exhibits an additional unique phenomenon of ghosting which results in blurry and low-texture images. Here, we provide a detailed view of thermal physics-driven texture and explain why it...

Thermal Voyager
