Second-harmonic excitation of a Gould—Trivelpiece mode in a beam-plasma system
Abstract
A Gould-Trivelpiece mode at significant power levels is excited in a cylindrical beam-plasma system by launching an external signal. The fundamental mode excites a second-harmonic wave in the upper-hybrid mode. When the second-harmonic frequency is close to (where is the upper-hybrid frequency), considerable enhancement in the second-harmonic power level is observed. The results are interpreted using a slab model.
