A radio signal nearly 9 billion light-years away from Earth was captured in a new recording, detected by India's Giant Metrewave Radio Telescope. McGill University said in a release that this marked ...
Visible light is just one part of the electromagnetic spectrum that astronomers use to study the universe. The James Webb Space Telescope was built to see infrared light, other space telescopes ...
Christopher Gordon De Pree has received funding from National Science Foundation. Christopher R. Anderson receives funding from the National Science Foundation, Office of Naval Research, and National ...
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 ...
To meet an increased demand for canceling radio frequency (RF) signal interference, L3 has built a system that can do just that and is planning to expand it into a software capability. L3 is already ...
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 ...
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 ...
