| 摘 要： | We develop a numerical model to investigate the localization of surface-exciton polaritons in the presence of random roughness and spatial dispersion.It is found that the localication occurs in a limited frequency range near the maximum frequency of surface-exciton polaritons.The decaying length in the extended region is much larger than that in the localized region.The localization of surface-exciton polaritons is due to the destructive interference between waves scattered from the rough surface.
