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 ...

The ubiquitous nerd in khaki pants and glasses makes it look so easy ” a seamless network of nationwide wireless access, a utopia of coverage where dropped calls are but a bad memory. Reality, as any ...

Unforeseen RF transmission impairments, such as cordless phones that use the 2.4GHz band, can cause frustration when deploying wireless LANs. In order to maintain happy users, it’s a good idea to ...

The following is excerpted from Chapter 5 of RF & Wireless Technologies by Bruce Fette. If you order a copy of this book before December 31, 2007 you can receive additional 20% off. Visit ...

It has long been appreciated that FM reception is vulnerable to multipath propagation. The effect of an echo for instance a reflection off a building is to create high-order harmonic and ...

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 ...
