A thin dielectric slab over a conducting sheet is presented as a low-loss slow-wave guiding system. When one introduces a magnetic wiggler into the system one may efficiently excite millimeter waves by passing a sheet electron beam just above the dielectric surface. For realistic parameters, the energy requirements on the beam are greatly reduced due to the wiggler. The frequency ω1 and the growth rate G are very sensitive to beam energy. G scales as IbB with beam current Ib and wiggler strength B0, and decreases with increasing width of the dielectric and increasing ω1.
