Compact Tuneable Terahertz Source

摘要

It has recently been proposed that a folded waveguide travelling wave tube could be constructed using silicon microfabrication technology. When configured as an oscillator this device could provide a high power ( > 100mW), highly efficient ( > 15%), reliable, compact and cheap source for the Terahertz Gap. This paper will present the current status of Liverpool John Moores University THz source. This will include theoretical and numerical simulations of the electron beam interaction with the electromagnetic waves (EM) and the design and construction of the EM wave interaction cavity. This research project is supported by the UK EMRS/DTC.
