Paper Abstract

It has been well recognized that, if the incident electromagnetic wave is linearly polarized parallel or perpendicular to grooves of a surface, the far-field scattering from a 1-D rough surface will have an identical polarization. We present recent experimental results and the comparative theoretical analysis that cover the enhanced backscattering from a characterized randomly rough 1-D vacuum/dielectric interface for p and s polarizations. It is believed that the observed enhanced backscattering results from the coherent interference of multiply scattered optical paths with their time-reversed partners when the wave vectors of the incident and scattered light are oppositely directed. This coherency is lost for scattering into directions other than the retroreflection direction.
