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 ...

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 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 ...

An international collaboration using the Low Frequency Array (LOFAR) has published an exceptionally detailed radio sky map, revealing 13.7 million cosmic sources and delivering the most complete ...

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 ...

Using the LOw Frequency ARray (LOFAR), astronomers from the University of Bologna, Italy and elsewhere, have conducted radio observations of the nearby galaxy cluster Abell 2142. In result, they ...

Phononic crystals (PnCs) are artificial structural composites with periodic modulation of elastic parameters, and they are capable of regulating the propagation of sound waves. Devices with different ...

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 ...
