A Graph Plotting Metal Detector. 31 Comments . by: Lewin Day. July 11, 2018. Title: Copy. Short Link: Copy. Metal detectors can be a great source of fun, and occasionally even found wealth.

Terhertz radiation, a form of light with wavelengths longer than infrared rays, could be used to easily examine people and products. A new detector may bring that technology to the marketplace.

Researchers from the Graphene Flagship have developed a novel graphene-based infrared (IR) detector demonstrating record high sensitivity for thermal detection. Graphene's unique attributes pave ...
