A linearized field theory of a groove-loaded folded waveguide traveling wave tube (FWTWT) is developed. The influence of groove dimensions and beam parameters on the linear gain and bandwidth of the device is investigated by numerical calculation. In addition, a comparison of the linear gain properties between the groove-loaded FWTWT and the conventional one is also carried out. It is indicated from the investigation that by the groove loading, the electric field that acts on the electron beam is enhanced, the electron beam gives more energy to wave, and the linear gain is raised.
