Abstract :
The interaction of the electromagnetic wave and the electron beam is studied. Finite difference method is used to study the interaction of the pulsed electron beam with RF fields of dielectric loaded waveguide. The dielectric loaded waveguide slow down the EM wave. When the velocity of both EM wave and the beam is comparable then a fruitful interaction takes place. It is observed that the strength of interaction depends on the detuning between the wave and beam. If velocity of the beam is greater, than the energy transfer takes place from beam to wave and the wave grows in amplitude.
