Hamid A. The approximate nonlinear theory of relativistic and non relativistic autophase devices of superhigh frequencies

The dissertation is devoted to create an approximate nonlinear theory and engineering methods for calculating autophase devices of superhigh frequencies - a new class of electron-vacuum powerful relativistic and non relativistic devices of superhigh frequencies in which basis of work the phenomenon of full capture electrons a field of an electromagnetic wave. By means of the analysis of physical processes the basic features of interaction in autophase lamps of a progressing wave with azimutally nonsymmetric field (ATWT) and in autophase lasers on free electrons (AFEL) are allocated. Preservation only these features in the mathematical description of this interaction has allowed to simplify sharply the initial equations of movement and high frequencies fields.
