Design the output window for Terahertz Extended Interaction Oscillator

Abstract

Extended Interaction Oscillator (EIO) is a promising Terahertz (THz) high power source, which has many important applications, such as military radar, medical imaging and material science research, etc. For the improvements Terahertz wave traversing, the output window for THz EIO is studied through the S parameter, including the thickness, geometry profile and place position, etc. The results show that one can gain the high transmission through the optimum parameter with thickness 0.4mm, diameter D is 5.0mm and the circular waveguide is 1.9mm.
