Description

We develop a numerical model to investigate the localization of surface exciton polaritons in the presence of random roughness and spatial dispersion. The localization criteria are examined. The localization effects are embodied in the large enhancement and rapid decay of the field intensity on the surface. The calculation shows that there is a transition from the localized state to the extended state. It has been found that the localization occurs in a limited frequency range above the resonant frequency of transverse excitons
