orotron

Investigation and development of efficient electromagnetic oscillations sources are one of the topical issues in the field of terahertz radiophysics and electronics. A frequency region is regarded as an explored for which oscillating, amplifying and measurement devices have not been developed. The exploration of the terahertz frequency range is at the initial state.

The peculiarities of the orotron double-row electrodynamical system and methods of output power increase were investigated. For the first time in the experimental model of orotron with electrodynamical system consisting of double-row plain periodic structure (DRPS) and sphere-cylindrical focusing mirror the possibility of using wide electron beam in order to output power increase in 140...300 GHz frequency range is demonstrated.
