Reseachers at ETH Zurich have developed a modulator with which data transmitted via millimetre waves can be directly converted into light pulses for optical fibres. This could make covering the "last mile" up to the internet ...
Electrical and optical engineers in Australia have designed a novel platform that could tailor telecommunication and optical transmissions. Collaborating scientists from the University of New South Wales in Sydney and Canberra, ...
Researchers at Duke University have devised a way to see through walls using a narrow band of microwave frequencies without any advance knowledge of what the walls are made out of. Besides having obvious applications in the ...
A major new international research programme is responding to the overwhelming demand of internet traffic to develop ubiquitous wireless data coverage with unprecedented speed at millimetre waves.
In a recent experiment at EPFL, a microwave resonator, a circuit that supports electric signals oscillating at a resonance frequency, is coupled to the vibrations of a metallic micro-drum. By actively cooling the mechanical ...
Researchers have created a new magnetic mirror-based device that could one day help cosmologists discover new details about ripples in space-time known as gravitational waves, particularly those emitted when the universe ...
Spintronics researchers have developed a phase locked loop (PLL) circuit designed to stabilize the oscillation frequency of a spin torque oscillator (STO), and demonstrated generation of a highly coherent microwave signal ...
Researchers from the Physikalisch-Technische Bundesanstalt (PTB) have thoroughly analyzed the noise processes in their optical lattice clock with neutral strontium atoms. This analysis proves that their optical atomic clock ...
Researchers from The University of Western Australia and Humboldt University of Berlin have completed testing that has effectively measured the spatial consistency of the speed of light with a precision ten times greater ...
(Phys.org)—A small team of researchers working at Aalto University in Finland has discovered a way to create "metamirrors" capable of acting on a single radiating frequency while allowing others to pass through. In their ...
