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 ...

Researchers were able to control the behavior of various light frequencies that passed through a specially designed cavity. The successful experiment can pave the way fiber optic advances that offer ...

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.

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 ...
