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 ...

Building a mesh router system isn't a number's game.

With many smartphones costing upwards of $1000 (and even budget phones costing several hundred dollars), most of us want to do all we can to protect our investment. A common way to do that is to buy 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 ...
