Abstract
Gyroklystron amplifiers are simulated using MAGY code, a self-consistent, time dependent code based on the reduced description of the electromagnetic fields and the electron beam in a cylindrically symmetric waveguide with an arbitrary wall radius. The fields are represented by the transverse electric and transverse magnetic modes which are coupled by the variations of the wall radius, and by the electron beam. The mode coupling due to radius variation is shown to depend on the logarithmic derivative of the wall radius as a function of the axial position. For a proper simulation of the mode coupling at a jump discontinuity, the coupling matrices are replaced by those which are computed on the basis of the mode matching transformation.
