MOVING PLATES CREATE NEGATIVE-FREQUENCY PHOTONIC RESONANCE

When in relative motion, plates of a Fabry-Perot interferometer generate a unique resonance with negative frequency if separated by a gap of critical size. We commonly encounter the idea of negative frequencies while analyzing electromagnetic waves and signals, which are often helpful as a...

NEW ANTENNA TECH TO EQUIP CERAMIC COATINGS WITH HEAT RADIATION CONTROL

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...

Thermal Night Vision

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 enhance camera vision faces difficulties when the number of intelligent agents scales up. Exploiting...

TeX Vision

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

Achieving reliable autonomous navigation during nighttime remains a substantial obstacle in the field of robotics. Although systems utilizing Light Detection and Ranging (LiDAR) and Radio Detection and Ranging (RADAR) enables environmental perception regardless of lighting conditions, they face...
