Every rideshare pickup, 911 call, and tractor guidance system depends on a single requirement: a GPS receiver must lock onto ...
Interoperable multipath hemispherical map (MHM) using overlap-frequency signals across constellations. The top panel shows the flowchart for modelling and correcting multipath in interoperable MHM.
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 ...
Every smartphone, aviation system, and fleet tracker on the planet depends on the same core trick: a receiver times radio ...
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 ...
