The obtained results demonstrate that the proposed virtual cathode oscillator “nanovircator” may be considered as the promising compact sub-THz radiation source that has a simple construction and operates in the absence of the external magnetic field.
Plans and perspectives
• Critical current lowering; • Full-scale mathematical optimization of existing “nanovircator” scheme in CST PS (geometry and beam optimization); • Detailed emission simulation (field emission);
• Analysis of external signal input posibility; • Simulation of coupled “nanovircator” cluster*.
