(Nanowerk News) A terahertz transmitter developed at the TU Darmstadt has generated the highest frequency ever attained by a microelectronic device. The minuscule device operates at room temperature and paves the the way for new applications.
Terahertz (THz) electromagnetic radiation has wavelengths between the ranges of 0.1 mm and 1 mm. At this frequency they can penetrate materials, such as plastics, paper, fabrics, or ceramics. No need to explore or examine the interior contents or workings of a while host of objects and mechanisms.
Possible uses include analyzing processes occurring in engine combustion chambers while engines are running, inspecting packages and letters for hazardous biological substances without need for opening them.
