Light scattering and its propagation through the PLZT ceramics is presented at the phase transition. TMM is applied to this structure, as a computational method for light scattering. This method is described in detail computational light scattering by polydispersive, randomly oriented rotationally symmetric particles. Our results associated with light wave propagation within the ferroelectric materials. The transmitted and the scattered intensities of incident plane wave are calculated for various combinations and geometry via to different parameters. Also, ferroic correlation between the PLZT structure and the light scattering is briefly discussed.
