Abstract: An exact solution to the quartic equation in the wiggler frequency ww, which represents the dispersion relation for this system, is obtained. The effects of the frequency of the wiggler ww on the electron's velocities (v\vert \vert and vw) are investigated. The regions of interest for the allowed wiggler frequency ww for both group I and group II electron trajectories are discussed.
Key Words: Free-Electron Laser (FEL), electromagnetic wiggler, wiggler frequency, reverse guide magnetic field
