On-demand control of stable toroidal vortices lays groundwork for robust wireless data encoding. (Nanowerk News) Researchers have created an optical device that can generate both electric and magnetic ...

Over the past decades, electronics engineers have been trying to develop increasingly smaller devices that can store ...

Permanent magnets aren’t typically switchable. They’re always doing their magnet thing. However, if you align them with a bunch of other magnets in just the right way, you can create a permanent ...

Researchers used a nonlinear metasurface to experimentally demonstrate skyrmions that can be switched between electric and magnetic modes in free-space toroidal terahertz light pulses. WASHINGTON — ...
