When you make conducting wires thinner, their electrical resistance goes up. This is Ohm’s law, and it is generally right. An important exception is at very low temperatures, where the mobility of ...

A research team including Assistant Professor Taichi Goto of Toyohashi University of Technology has conducted simulations to demonstrate that using a substrate that combines the semiconductor silicon ...

Thanks to a breakthrough in the field of magnonics, researchers have sent and stored data using charge-free magnetic waves, rather than traditional electron flows. The discovery could solve the ...

Future wireless networks will need to process far more data across a wider range of frequencies than today’s systems. This ...

Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency bands for mobile communications, Wi-Fi, and GPS in smartphones. Physicists ...
