In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

Alpha waves are electromagnetic oscillations in the frequency range of 8-12 Hz arising from synchronous and coherent (in phase / constructive) electrical activity of large groups of neurons in the ...

Researchers have now succeeded in producing an extremely simple and compact source of terahertz radiation: An oscillator with double resonant-tunneling diodes. Its radiation power significantly ...

A research team from the NUST MISIS Laboratory of Superconducting Metamaterials led by Alexey Basharin, Senior Lecturer and Candidate of Technical Sciences, has developed a metamaterial-dielectric ...

Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, ...
