The aim of the present paper is to address the issues whether it is possible to design and develop by numerical simulation the electromagnetic continuous-wave THz-sources width electrically tunable frequency. These sources may well find their use, in the fields of applications such as the development of THz spectroscopy, high-resolution radars, and communication lines between super, high-speed computers...
The chain of equivalent quadripoles as mathematical model of BWO on wavy bent rectangular waveguides are used. Results of optimization of relativistic cm-band BWO with accelerating voltage 400...1000 kV, currents 0.25...5 kA, as well as mm and sub-mm BWO are represented
Generators for a millimeter and sub-millimeter wavelengths range with the use of klystrons principle of interaction are presented. It is shown, that the calculated electron efficiency of orbotron-klystrons on frequencies 50-300 GHz reaches up to 16-54%. Output power of klystron-frequency multipliers reaches 2.6-39 W on frequencies of 500-2000 GHz
