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 ...

A frequency-agile meta-material that for the first time can be tuned over a range of frequencies in the so-called "terahertz gap" has been engineered. The team's first-generation device achieved 20 ...

Electromagnetic waves with frequencies between microwave and infrared light, also known as terahertz radiation, are leveraged ...

Dennis G. Hall is a licensed amateur radio operator and a professor emeritus at Vanderbilt University. An old joke asks: what washes up onto tiny beaches? The answer is microwaves. In truth, we are ...

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 ...

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 ...

Cambridge, MA – Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify ...
