In this paper, the small signal gain of a folded waveguide travelling wave tube (FWTWT) is calculated by means of Madey's theorem. The results of this analysis were compared with a single particle simulation carried out with MATLAB. The results were in excellent agreement. The calculations indicate the great potential of this device as an oscillator in the terahertz regime.

The objectives of this European project are to use high frequency microwave technology to develop focussed energy sources for industrial applications. The microwaves, generated in the 10GHz to 20GHz frequency range by using a table top FEM has been used to investigate novel solutions for material processing and material production, including microwave heating of substrates, microwave chemistry for increasing the speed of thermal reactions, microwave plasma chemistry for aiding gaseous reactions in the reduction of combustion pollutants and the production of UV/ozone for germicidal activities. In this paper we report unique results and analysis in using tuneable FEM system compared with the conventional magnetron 2.45 GHz system.
