For any disordered medium (such as a sugar cube, for example), special light waves can be found which are practically not changed by the medium, only attenuated. These 'scattering invariant light ...

In the dynamic realm of optical physics, researchers are continually pushing the boundaries of how light can be manipulated and harnessed for practical applications. As reported in Advanced Photonics ...

A new beam pattern devised by University of Rochester researchers could bring unprecedented sharpness to ultrasound and radar images, burn precise holes in manufactured materials at a nano scale -- ...

Scientists in China have developed a metasurface platform that realizes true three-dimensional (3D) vectorial holography by ...
