We’ve talked about this tiny gadget before: the Flipper Zero. Officially, it’s a $170 tamagotchi-fied hacking gadget with a sub-gigahertz radio and some accessory pins. Unofficially, it’s a menace’s ...

In nanophotonics, tiny structures are used to control light at the nanoscale and render it useful for technological applications. A key element here is optical resonators, which trap and amplify light ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Researchers report their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits.
