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 ...

An international research team led by Drexel University found that thin coatings of MXene nanomaterials can enhance a material’s ability to trap or shed heat. MXenes, a two dimensional material first ...

Non-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF) and extremely low frequency (ELF). Lasers commonly operate in the ...

With today's data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: Magnetic ...

The design and principle for the proposed infrared-blocking glasses (left), and two of the co-authors, Alexander Govorov (the lead) and Lucas V Besteiro (the first author of the study). Courtesy: ...

For a long time, scientists have been looking for simple methods to produce infrared laser pulses. Now a new method has been presented that does not require large experimental setups; it can be easily ...

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 ...

Wet comb: NIST’s tabletop frequency comb being used to identify water molecules in air. The yellow squiggle at the top of the screen is the electric field of mid-infrared laser light that has passed ...
