Plasma antennas represent a transformative approach in the manipulation and propagation of electromagnetic waves. By utilising ionised gases instead of traditional metallic elements, these antennas ...

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 ...
