Abstract
A pulse of terahertz radiation is transmitted through a touch panel formed of a dielectric material. The pulse generates an employable evanescent field in a region adjacent to a touch surface of the touch panel. The terahertz radiation has a frequency range between 0.1 terahertz and 10 terahertz. A reflected pulse is generated from an object located within the region adjacent to the touch surface of the touch panel. A position is triangulated of the object on the touch surface of the touch panel, based at least in part on the reflected pulse.
