Abstract :
A linear theory of bilateral metal-grating periodic slow-wave structure (SWS) with a sheet electron beam is developed. The field-matching method has been used at the upper and bottom waveguide boundaries where the metal-grating structure is used to slow down the electromagnetic phase velocity. The derived dispersion equation has been solved through the iterative technique. The influences of the structural asymmetry on the linear growth rate have been analyzed as well.
