Higher frequencies mean faster data transfer and more powerful processors. Technically, however, it is anything but easy to keep increasing clock rates and radio frequencies. New materials could solve ...

Silicon semiconductors are widely used as particle detectors; however, their long-term operation is constrained by ...

Modern technology uses many frequencies of electromagnetic radiation for communication, including radio waves, TV signals, microwaves and visible light. Now, a University of Utah study shows how ...

Components of a typical laser include gain medium, laser pumping energy and resonant optical cavity. The output frequency of most lasers is fixed or within a small range, and it is difficult to ...

Containing the electromagnetic radiation generated by electronic components is a key consideration for designers of electronic devices, but today’s metal-based shielding materials have their downsides ...

Add Yahoo as a preferred source to see more of our stories on Google. But behind these lights lurks an invisible — and much more problematic — form of radiation: radio waves. If our eyes could also ...
