Study finds photons can show a quantum Hall effect under strong fields
Physicists have for the first time observed light drifting sideways in discrete, quantized steps, reproducing a quantum Hall ...
Traditional radio-based systems often suffer severe attenuation underground, as soil and rock absorb or scatter electromagnetic waves. By contrast, magnetic induction uses low-frequency magnetic ...
Allegro has added magneto-resistive sensors to its Hall-based range of current and magnetic field devices, for high-sensitivity high-bandwidth applications. The first product is a 5A 1MHz isolated ...
A professor provides a new theoretical mechanism that explains the ability of superconductive materials to bounce back from being exposed to a magnetic field. This work may lead to energy systems that ...
PC-board layout sets the functional, electromagnetic interference (EMI), and thermal behavior of a power supply. Good layout from first prototyping on actually saves significant resources in EMI ...
