Features of the new version of the fast wave gyro-device simulation code MAGY will be discussed. Examples of its application to the study of multifrequency processes occurring in fast wave devices will also be presented. The goal of the current development efforts was to make the code capable of analyzing multifrequency regimes of fast wave device operation. In particular, the code can treat an arbitrary set of temporal and cyclotron harmonics as well as sets of equally spaced in frequency electromagnetic. Other features include treatments of losses due to the presence of absorbing materials, a realistic profile of guiding magnetic field, and azimuthal inhomogeneity of the electron beam with a local velocity spread. Examples of simulations conducted using the new version of MAGY include: Frequency multiplication in the University of Maryland and NRL gyro klystron multipliers, higher temporal harmonic excitation in the NRL gyro klystron, mode competition in gyrotrons for fusion, and parametric mode coupling due to non-homogeneity of electron beam.
