Abstract :
The dynamics of the composite grating is investigated using numerical calculations including the effects of beam coupling. Both nonuniform distribution of the space charge field and the fringe bending result in the residual grating after the erasure process. Simple analytical solutions which neglect beam coupling effects will be compared with the simulation results in terms of memory applications at the presentation
