The double-mode teragertz oscillator with the nonuniform focusing field

Abstract

Theoretical investigation of the effect regularities of the nonuniform focusing field on the double-mode oscilla- tor characteristics with two output multiple frequencies signals is carried out in this work. Analysis is performed on the basis of the nonlinear multidimensional theory of the O-type resonant electron devices with prolonged interaction with taking into account the settling of electrons on the slow-wave structure surface. Values of the magnetic field lo- cal nonuniformity parameters that correspond to beam-wave interaction efficiency enhancement at higher harmonics of the electron beam bunching frequency are determined.
