Researchers created a new graphene device that will unleash new and elusive frequencies in the electromagnetic spectrum. According to a phys.org report, the device will give scientists access to terahertz wavelengths, which makes revolutionary technologies possible.

More familiar to most are microwaves and infrared—both wavelengths of light that fall below the visual spectrum. Likewise below our basic sense perception, terahertz waves (THz) exist between them, and are low-enegy, which makes it difficult for scientists to harness their energy and repurpose it for technology. This problem is called the "terahertz gap."

In the past, closing the terahertz gap was impossible because, with a range between 30mm and 30µm, THz-wave (T-ray) signals were too weak for practical use.

This new capability to detect and amplify T-rays will usher a new age of medical, communications, satellite, and even cosmological tech.
