Diffraction theory describes how wave fields—acoustic, electromagnetic or quantum—interact with obstacles and apertures, producing characteristic patterns of scattering and interference. At its heart ...

The study of electromagnetic diffraction and scattering in metamaterials encompasses how artificially structured materials manipulate wave propagation at scales comparable to or smaller than the ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has been pushed even further. For the first time, researchers have observed ...

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...

Often people working in optics and photonics confuse geometric optics with wave optics, but they aren’t the same thing! Geometric optics treats the propagation of light in terms of “rays”, where each ...

A collaborative research team led by Interim Head of Physics Professor Shuang Zhang from The University of Hong Kong (HKU), along with National Center for Nanoscience and Technology, Imperial College ...
