Optimization of 0.1 THz Planar Interaction Structure for Higher Efficiency

In this paper, simulation studies on 0.1 THz planar slow wave interaction structure for Backward Wave Oscillators (BWOs) have been presented. The normalized phase velocity and dispersion variation profiles for different beam tunnel width to height ratios are analyzed using Eigen mode simulations in CST Microwave Studio. Axial electric field amplitude with interaction impedance profile for different aspect ratios, are also analyzed as a optimization study of effect of beam tunnel width to height ratio with the BWO operation and its frequency range.
