Abstract :
The paper describes the use of numerical methods to precisely predict the characteristics of ring-Loop & ring-Bar slow wave structures and provides examples of the close agreement obtainable between predicted and actual measured performance of TWTs. The microwave properties of the structures have been modelled using a commercially available 3D, high frequency electromagnetic, software package, founded on use of the finite element method.
