Metamaterials made of magnetic photonic crystals have been generated and tuned to a theoretically predicted transition point at which peculiar optical properties emerge. For example, when light is ...

under the MIT license on GitHub, uses WebGL to display three-dimensional computer graphics on a web browser, and it is possible to create multicolored complex vortices by fluid simulation. Tool to ...

Smoke rings are being seen in a new light. Doughnut-shaped structures called vortex rings are sometimes seen swirling through fluids. Smokers can form them with their mouths, volcanoes can spit them ...

Researchers said these optical vortices could help overcome bandwidth limitations in fibre optic communication, or enhance the optical tweezers that can manipulate atoms. Researchers have created an ...

A complex maze of lasers, lenses and mirrors has been used to twist light into a vortex shaped like a doughnut. Vortex rings are common in fluids – think of smoke rings floating in air or underwater ...
