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 ...

To meet an increased demand for canceling radio frequency (RF) signal interference, L3 has built a system that can do just that and is planning to expand it into a software capability. L3 is already ...

Satellites depend on radio frequency spectrum to communicate with each other and with ground stations on Earth, but spectrum is a finite resource that’s prone to interference — an issue that’s only ...
