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.

An artistic pressions of a vortex-ring street analogue to the structure of magnetic field of a NDSTP, where the right- and left- handed vortex rings were highlighted by blue and red, respectively. The ...

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 ...

The study of vortex ring dynamics centres on understanding the formation, evolution and decay of toroidal vortices generated by pulsed fluid jets. These phenomena are crucial in a wide range of ...
