When British physicist Roger Penrose suggested in 1969 that energy could be pulled from a rotating black hole, it sparked a ...

A metasurface-based approach is proposed for single-shot optical imaging that simultaneously captures all the three ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter.

Abstract: Vortex electromagnetic (EM) waves hold significant promise for next-generation wireless communication applications. However, their practical deployment is hindered by varying divergence ...
