Light, as an electromagnetic wave, possesses several fundamental properties, which include intensity, wavelength, phase and polarisation (the direction in which the light waves oscillate). While the ...

Metasurfaces are planar assemblies of subwavelength resonators engineered to tailor amplitude, phase and polarisation of electromagnetic waves. In the terahertz domain (0.1–10 THz), they offer a ...

Terahertz (THz) waves are located between microwaves and infrared light in the electromagnetic spectrum. They can pass through many materials without causing damage, making them useful for security ...

Polarization imaging exploits the vectorial nature of light to reveal scene features inaccessible to conventional intensity sensors. By analysing the orientation and ellipticity of the electric field, ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.230180, discusses orthogonal matrix of polarization combinations: concept and application to multichannel holographic recording.

Ferroelectric crystals are a special class of materials that exhibit spontaneous electric polarization, which can be reversed by applying an external electric field. These crystals have a ...

Imagine a camera that's mounted on your car being able to identify black ice on the road, giving you a heads-up before you drive over it. Or a cell phone camera that can tell whether a lesion on your ...
