A light-controlled meta-surface redirected another beam at femtosecond speeds without relying on slower electronic relaxation ...

A team of astronomers studying superluminous supernova SN 2024afav has detected a periodic, accelerating signal in its light ...

Two experiments designed to detect signals directly found no evidence for the signal reported by an earlier experiment.

A black hole is not sitting inside a lab in Manhattan, but some of its strangest physics just helped shape a tabletop experiment there. For decades, physicists have wondered whether waves could steal ...

Abstract: Ground moving target indication (GMTI) in the synthetic aperture radar (SAR) system enables high resolution, all-weather, and all-day imaging and detection of moving targets, posing a ...

Abstract: Metasurfaces can degrade radar pulse compression (PC) performance by encoding radar echoes with time-domain random phase modulation (RPM), which alters the correlation between the echo ...
