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 ...
The Planck collaboration, which includes the CNRS, the French Alternative Energies and Atomic Energy Commission (CEA), the French National Space Agency (CNES) and several French universities and institutions, has today released ...
Researchers from the National Institute of Standards and Technology (NIST) and California Institute of Technology (Caltech) have demonstrated a new design for an atomic clock that is based on a chip-scale frequency comb, ...
Wireless transmission at microwave frequencies is important for high-data-rate transmission applications, such as mobile phone networks, satellite links and remote imaging. Now, Xianshu Luo and colleagues from the A*STAR ...
