Interference-free GNSS signals are essential for more than just military vehicles and aircraft. Anti-jam systems usually suppress signals from interference sources by means of spatial filtering. These ...

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 ...

Even in the best designs, noise and interference sneak in to reduce the signal-to-noise ratio (SNR), obscure desired signals, and impair measurement accuracy and repeatability. Digitizing instruments ...
