Scientists scale terahertz peaks in nanotubes
(Phys.org) —Carbon nanotubes carry plasmonic signals in the terahertz range of the electromagnetic spectrum, but only if they're metallic by nature or doped.
Nanoscale 'tsunami' helps locusts tune in
The remarkable mechanism by which the tiny ears of locusts can hear and distinguish between different tones has been discovered by researchers from the University of Bristol.
Work begins on world's most powerful radio telescope
This week, work begins on the next phase of development for the Square Kilometre Array radio telescope, with the University of Cambridge leading major 'work packages'.
Vibrating micro plates bring order to overcrowded radio spectrum
GSM, WiFi, Bluetooth, 4G, GPS: a smartphone already has to handle many wireless standards. And this number will only increase further. There are still no good filters to keep all those future standards separate. ...
Watching the heart beat of molecules
A team of scientists around Prof. Theodor W. Hänsch and Dr. Nathalie Picqué at the Laser Spectroscopy Division of the Max Planck Institute of Quantum Optics (Garching), in a collaboration with the Ludwig-Maximilians-Universität ...
Innovative wideband ring voltage-controlled oscillator (VCO)
A new wideband ring voltage-controlled oscillator (VOC) was proposed by UNIST undergraduate student, Seyeon Yoo with the the research work published in IEEE Microwave and Wireless Components Letters.
New level for continuous-wave terahertz lasers
Since the first quantum cascade (QC) laser was demonstrated in 1994 and implemented in THz regime in 2002, they have become one of the most important solid state light sources in this frequency range. The ...
Optical wireless may be the answer to dropped calls, and more
Anyone who has tried to make a cell phone call from a crowded football stadium has had a taste of what engineers call spectrum crunch.
Measuring height by connecting clocks
How far above sea level is a place located? And where exactly is "sea level"? It is one objective of the geodesists to answer these questions with 1 cm accuracy. Conventional measurement procedures or GPS ...
Detected radio bursts evidence of 'exotic phenomena'
The detection of four short bursts of radio waves, possibly arising from explosions billions of light years away, could be powerful tools to study our Universe, according to research published in Science.
Spirals of light may lead to better electronics
(Phys.org) —A group of researchers at the California Institute of Technology (Caltech) has created the optical equivalent of a tuning fork—a device that can help steady the electrical currents needed ...
Research team develops tattoo-like skin thermometer patch
iPhone 5S fingerprint scanning: Thumbs up or down?
Technology to acquire and use biometric data such as fingerprints has been around for several decades and has made its way from forensic investigation to laptop computers – and now, with this week's introduction ...
Device gives scientists front-row seat to lightning strikes
A device developed at The University of Alabama in Huntsville (UAH) has become a valuable tool in researchers' quest to determine how lightning is spawned in clouds, to map strikes from beginning to end and ...
