N2 - Experiments and theoretical estimates demonstrate the existence of surface plasmon polaritons (SPPs) in the terahertz (THz) frequency range with a field localized near the surface of the conductor and propagating along the surface with relatively low losses. This fact opens up a possibility of generating SPPs by organizing their “direct” excitation near the metal surface, for example, due to stimulated cyclotron emission from electron beams. This can be a way for realization of THz gyrotrons based on selective excitation of SPPs at high cyclotron harmonics inside special open cavities. In this work, a possible scheme of a plasmonic gyrotron is proposed, the simplest theory of electronic cyclotron excitation of a SPP wave in an open cavity is described, and estimates for the starting currents of possible plasmonic gyrotrons are given.
