There is a common element to every radio system, be it transmission or reception, and that is the antenna. But even though it is an essential system component, historically it’s been the least ...

Researchers at the University of Warsaw have unveiled a breakthrough method for detecting and precisely calibrating terahertz ...

A research team has created a quantum antenna capable of precisely measuring terahertz frequency combs for the first time. A research team from the Faculty of Physics and the Centre for Quantum ...

Bi-stable: The helix-based antenna switches between its two operating modes as it contracts (left) and extends (right). (Courtesy: Reconfigurable & Active Structures Lab) A lightweight, easily ...

A new simpler, cheaper and potentially more effective way to prevent radio antennas from picking up unwanted signals has been created by researchers in the US. With further development, the technique ...

We all use antennas for radios, cell phones, and WiFi. Understanding how they work, though, can take a lifetime of study. If you are rusty on the basic physics of why an antenna radiates, have a look ...

What's the optimal orientation of an antenna broadcasting and receiving on a wireless access point? Could it be anything other than vertical? Is it dependent on the environment and the surrounding ...

Though it was hailed as a triumph for the "Standard Model" of physics – the reigning model of fundamental forces and particles – physicists were quick to emphasize that last year's discovery of the ...
