Abstract :
The Terahertz gap in EM spectrum has found potential applications in high data rate communication, electronic materials, spectroscopy, medicines, biosciences, space research and remote sensing of public and strategic areas. For the generation of THz radiation with medium power many compact vacuum microelectronics/ MEMS technology based devices such as TWTs, Klystrons etc are being tried out. CEERI jointly with Technical University Berlin has been pursuing design and development of W-Band folded Waveguide TWT. Folded Waveguide structure has been chosen because of its robust construction, high power handling capability, simpler coupling and reasonable wide bandwidth. Design of W-band Folded Wave Guide RF structure has been completed using CST-MWS1and GdfidL2 simulation codes. As well in house developed SUNRAY 1-D3Large Signal Code. Simple Waveguide Coupler with reference to its construction through micro-EDM as well as LIGA techniques has been designed with the excellent cold test performance. Initially a moderate circuit length (55mm) has been taken with reasonable gain.
