Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a ...

This video presents a study in which researchers developed a passive metasurface that uses a time-varying interlocking mechanism with metal-oxide-semiconductor field-effect transistors to selectively ...

In a groundbreaking observation, astronomers have detected the first ever radio signal from the interstellar comet 3I/ATLAS, an object originating from outside our solar system. This unusual signal ...
