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

Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, ...

Abstract: LLC resonant converters are widely used in wide power range applications. However, their switching frequency will be much higher than normal load when they are applied under extreme light ...

Abstract: Deep-learning-based structured light 3D reconstruction technology (SL3D) provides excellent solutions for intelligent manufacturing. However, the scarcity of real-world datasets covering ...

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

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