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 ...

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 ...

Fig. 1 | Schematics of the PA-PSO algorithm. (a) and (b) Working principle of the metalens antenna. (c) and (d) Comparison between the traditional PSO and PA-PSO algorithm. The red and blue stars ...

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 ...

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

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 ...

A new device that collects and focuses light before converting it into a current of electrons has been developed by researchers at Rice University in the US. The nano-optical antenna and photodiode – ...

Tech blog Anandtech goes hands-on with the iPhone 4, iPhone 3GS, and Nexus One to find out if the antenna issue is unique to the iPhone 4's hardware or software. Erica Ogg is a CNET News reporter who ...

The pursuit of next-generation technologies places a premium on producing increased speed and efficiency with components built at scales small enough to function on a computer chip. One of the ...

In making the most precise measurements ever of the shape of electrons, a team of Harvard and Yale scientists has raised severe doubts about several popular theories of what lies beyond the Higgs ...
