Researchers report that lab tests of a new metasurface-based antenna that can harvest 100 microwatts of power, enough to power simple devices, from low power radio waves. This represents an important ...

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 ...

A new ultra-low-power method of communication at first glance seems to violate the laws of physics. It is possible to wirelessly transmit information simply by opening and closing a switch that ...

RF antennas serve as an important link between user terminals and communication base station equipment. Radio waves, which are central to this process, are electromagnetic waves that propagate at a ...

It is perhaps humanity’s most defining trait that we are always striving to build things better, stronger, faster, or bigger than that which came before. Taller skyscrapers, longer bridges, and ...

When temps start to rise, and everyone wants to have fun in the sun, owning a boat can be a great way to cool off and enjoy an adventure with family and friends. You can get a great deal, especially ...

As far as data security is concerned, there is an even greater danger than remote cyberattacks: namely tampering with hardware that can be used to read out information – such as credit card data from ...

University of Otago 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 ...
