THz Devices

THz applications require compact and powerful sources and amplifiers. The synergy between vacuum electronics working principles and novel high aspect ratio fabrication technology is leading to miniature tubes which represent the most promising solution to this need.

THz Vacuum Devices Corrugated or folded waveguide traveling wave tubes, backward wave oscillators, micro thermionic cathodes, and cold cathodes are but a sampling of current research in this area.
