Physicists in Low Temperature Laboratory of Aalto University have shown how a nanomechanical oscillator can be used for detection and amplification of feeble radio waves or microwaves. A measurement using such a tiny device, resembling a miniaturized guitar string, can be performed with the least possible disturbance. The......more
The research team, led by Professor Geoff Nash from the University of Exeter, have created a new structure that can manipulate the extreme frequency sound waves – also known as surface acoustic waves or ‘nanoquakes’ , as they run across the surface of a solid material in a similar manner to earthquake tremors on land.......more
Scientists based in the UK and the US have demonstrated for the first time how ‘twisted’ sound waves from a rotating source can produce negative frequencies, analogous to turning back time. A team of researchers from the Universities of Glasgow, Exeter and Illinois Wesleyan report in the journal Proceedings of the National......more
NSF joins leading networking companies and associations to support wireless research platforms in Salt Lake City and New York City The National Science Foundation (NSF) announces an important milestone in its Platforms for Advanced Wireless Research (PAWR) effort. In collaboration with an industry consortium of 28......more
