Radio astronomy has long been unsung and underappreciated, largely because it's never been able to cough up the kind of jaw-dropping visual images that are routine with large optical telescopes. But ...

The HFA3128 is an ultra high frequency transistor array that is fabricated from Intersil Corporation’s complementary bipolar UHF-1 process. Each array consists of five dielectrically isolated ...

The HFA is an acoustic "window" used in conjunction with the high frequency sail array. The primary purpose of an HFA window is to provide an acoustically transparent interface to seawater from the ...

More than 20,000 radio antennas will soon connect over the Internet to scan largely unexplored radio frequencies, hunting for the first stars and galaxies and potentially signals of extraterrestrial ...

A team of astronomers and engineers at ASTRON, the Netherlands Institute for Radio Astronomy, has successfully detected correlated interferometric radio signals, called “fringes,” from the sky with ...

Princeton researchers have taken a step toward developing a type of antenna array that could coat an airplane's wings, function as a skin patch transmitting signals to medical implants, or cover a ...

While these modeling results paint a potentially bleak picture, there is a very large degree of uncertainty in the space environments to which exoplanets are exposed. The biggest issue is the lack of ...

U.S. Naval Research Laboratory scientists from the Radio Astrophysics and Sensing Section of the Remote Sensing Division in conjunction with radio astronomers and engineers from the National Radio ...

As China's contribution to the world's largest intergovernmental international radio telescope project Square Kilometer Array Observatory (SKAO), the first batch of the China-built middle-frequency ...

Vibration, a fundamental mechanical stimulus, transmits dynamic signals that extend beyond quasi-static responses such as strain 1, shear 2 and pressure 3,4. Unlike these, vibration conveys unique ...
