A real-time system combining a simulator and a GNSS propagation model reproduces an authentic multipath environment. The propagation model relies on a 3D-model reconstruction of the urban environment, ...

The evolution of wireless communications and the miniaturization of electrical circuits have fundamentally reshaped our lives and the digital landscape. However, as we push toward higher-frequency ...

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 ...
