Excitation of electromagnetic surface waves by an annular electron beam in a plasma waveguide with a dielectric rod and a magnetized plasma column

The dispersion relation for symmetrical TM electromagnetic surface waves propagating in a plasma waveguide with a strongly magnetized plasma column and a dielectric rod is investigated. The growth rate for excitation of these waves is obtained and its dependence on the radius of the annular beam, current intensity and accelerating voltage are investigated.
