Abstract: An exact solution to the quartic equation in the wiggler frequency w_w, which represents the dispersion relation for this system, is obtained. The effects of the frequency of the wiggler w_w on the electron's velocities (v_{\vert \vert} and v_w) are investigated. The regions of interest for the allowed wiggler frequency w_w 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
