Abstract : This report summarizes results obtained in the study of how waves are reflected and transmitted by a randomly layered medium. We assume that temporally pulsed energy (plane wave, beam or radiated energy from a localized source) illuminates this material. Work that was initially done for the acoustic and electromagnetic problems is being extended in these two areas of application. The fundamental approach is also being applied to the elastic medium problem.
