Abstract
It is the first time to observe Photorefractive surface electromagnetic waves at the interface between SBN and air with a drift-diffusion mechanism experimentally. The conditions to produce the type of electromagnetic wave are: the incident beam should be at an angle of 55o in proper ratio of signal beam to background beam, and the intensity of PR SEW increases along with the increasing of additional electric field.
