A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

Small battery devices need magnetic switches that use power and take up space. These switches detect magnets and help devices run longer.

A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.

New device switches terahertz pulses between electric and magnetic skyrmions On-demand control of stable toroidal vortices lays groundwork for robust wireless data e ...
