ENHANCED BACKSCATTERING FROM A VOLUME-SCATTERING MEDIUM BEHIND A PHASE SCREEN

The enhanced-backscattering (EBS) phenomenon is investigated for the c ase in which a phase screen is placed close to a multiple-scattering m edium. This situation results in a narrowing of the EBS peak that depe nds on the strength and the position of the phase screen. The resultin g enhancement peak is essentially the sum of two contributions: the EB S produced by the multiple-scattering medium in the absence of the pha se screen and the enhancement obtained when the multiple-scattering me dium is replaced by a plane mirror.
