An Electromagnetic Vortex Cannon, Finally!
Researchers say they've found a way to createa freely propagating vortex ring, like a smokering, but with electromagnetic waves. Whydoes this even matter? What might thisdiscovery be used for? Let's take a look.

Abstract: We introduce a quantum mechanics inspired approach for the characterization of space-time non-separable waves, such as the Flying Doughnut pulse. We apply techniques analogous to quantum state tomography to quantify the type and degree of non-separability and provide quantitative predictions of the pulse propagation dynamics.
