Abstract: A nonlinear, nonstationary theory of relativistic surface-wave generators for the microwave range has been constructed in the framework of a quasi-optical approach. The radiation field is represented by two counter-propagating quasi-optical waves that are coupled at a corrugated surface so as to form an evanescent wave mode. A synchronous interaction with a straight sheet electron beam takes place with allowance for the surface wave retardation. An experimentally implemented prototype of the relativistic surface-wave generator operating in the millimeter range has been simulated and it shown that generators of this type can be developed so as to operate in the submillimeter range.
