An Adaptive Method of Complex Amplitudes in Spectral Simulations of the Electron Devices
RESUMO
A modification of known method of complex amplitudes is proposed to simulate the solenoidal fields in continuous slow-wave structure of the UHF vacuum devices. This is founded on permanent adaptation of base (i.e., carrier) frequencies of considered quasi-harmonic components of the fields to a present spectrum of the exciting current. This provides an essential increasing of a broadbandness of the spectral models based on this approach, with saving of all advantages of the complex amplitude method. The modification consists in continuous monitoring of the exciting current spectrum with regular adjustment of a set of the base frequencies. A domain of the adaptive method applicability is defined. An example of using of one for exploration of possible sources of spurious oscillations in the generating cross-field devices is given.
