When a superconductor is sandwiched between metal materials, a type of scattering called crossed Andreev reflection may appear, and in an s-wave superconductor junction, the Andreev reflection usually ...

Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses.

Researchers have developed a surprising method to eliminate wave reflections. The method allows the calculation of a tailor-made anti-reflective structure. It can be used, for example, to design an ...

Sketch of the concept: a disordered medium (top) is made perfectly transmitting by placing a custom-made anti-reflection coating in front of it (bottom). (Courtesy: TU Wien) A new technique that ...

Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...
