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 ...

In a novel experiment, physicists have observed long range quantum coherence effects due to Aharonov-Bohm interference in a topological insulator-based device. This finding opens up a new realm of ...

Satellites depend on radio frequency spectrum to communicate with each other and with ground stations on Earth, but spectrum is a finite resource that’s prone to interference — an issue that’s only ...

KIRKLAND, Wash. & MAKATI, Philippines--(BUSINESS WIRE)--Leading Philippine integrated telco PLDT’s wireless subsidiary Smart Communications, Inc. (Smart) and Spectrum Effect® announced today that ...

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 ...
