The speed of light can be intentionally reduced in various media. Various techniques have been developed over the years to slow down light, including electromagnetically induced transparency (EIT), Bose-Einstein condensate ...
Working in the terahertz (THz) range offers unique opportunities in various applications, including biomedical imaging, telecommunications, and advanced sensing systems. However, because of the unique properties of electromagnetic ...
A KAIST research team has developed an anti-icing and de-icing film coating technology that can apply the photothermal effect of gold nanoparticles to industrial sites without the need for heating wires, periodic spray or ...
Researchers have developed a new technology that uses meta-optical devices to perform thermal imaging. The approach provides richer information about imaged objects, which could broaden the use of thermal imaging in fields ...
National University of Singapore (NUS) researchers have introduced an upconversion plasmonphore platform to enable precise control over the polarization of isotropic upconversion nanoparticles (UCNPs). This is achieved by ...
Space coiling acoustic metamaterials are static and require manual reconfiguration for sound-field modulation. In a new report published in Communications Materials, Christabel Choi, and a team of scientists in computer science ...
A front-end lens, or meta-imager, created at Vanderbilt University can potentially replace traditional imaging optics in machine-vision applications, producing images at higher speed and using less power.
Flat optics are made of nanostructures containing high-refractive index materials to produce lenses with thin form factors that function only at specific wavelengths.
As object identification and three-dimensional (3D) reconstruction techniques become essential in various reverse engineering, artificial intelligence, medical diagnosis, and industrial production fields, there is an increasing ...
Computer-generated holography (CGH) represents a cutting-edge technology that employs computer algorithms to dynamically reconstruct virtual objects. This technology has found extensive applications across diverse fields ...
