Tel Aviv scientists predict ancient radio signals from the early Universe that could reveal how dark matter shaped stars and ...

Researchers propose that hydrogen gas from the early Universe emitted detectable radio waves influenced by dark matter.

The world’s first all-optical radio runs on laser light, not electricity, opening new possibilities for stealth sensors and satellite applications.

A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the University of Warsaw has developed ...

The new radio portrait of the Milky Way is the most sensitive, widest-area map at these low frequencies to date. It will ...

WASHINGTON — Researchers have developed a new metasurface-based antenna that represents an important step toward making it practical to harvest energy from radio waves, such as the ones used in cell ...

Physicists have used a small glass bulb containing an atomic vapor to demonstrate a new form of antenna for radio waves. The bulb was 'wired up' with laser beams and could therefore be placed far from ...

Maximum transmission efficiency occurs when the load impedance matches the generator impedance. Engineers do this to eliminate standing waves, which can severely damage equipment. Transmission lines ...

Imagine taking the radio frequency properties of the dish antennas you see on rooftops and knitting them into a wearable ...

In these low-frequency bands, the signals are not heard in loudspeakers or headphones, or rather, the emission of sounds could occur but it is not the main activity, as is normally the case on other ...
