Antenna arrays offer advantages in terms of spatial diversity, allowing for control over pattern specifications in space. The incorporation of frequency diversity in arrays presents an opportunity to ...

Photoacoustic tomography as an optical-ultrasound hybrid imaging modality provides rich optical contrast over the extended penetration depth of biological tissues, enabling multiscale multicontrast ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
