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 ...

Multipath mitigation is a critical area of research within Global Navigation Satellite Systems (GNSS) that addresses errors arising from signal reflections off surfaces before they reach a receiver.

Today, many wireless communications systems incorporate multiple input, multiple output (MIMO) antenna schemes to take advantage of the multipath signal propagation. In addition, many of today’s ...

Global navigation satellite systems (GNSS) are vital for positioning autonomous vehicles, buses, drones, and outdoor robots. Yet its accuracy often degrades in dense urban areas due to signal blockage ...

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 ...
