These contributions must be augmented by recent developments in the following three areas: (1) quantum mechanical potential scattering [Barabanenkov, 1976;Barabanenkov and Ozrin, 1976, 1978], which is analogous to electromagnetic scattering when particle sizes are large compared to the wavelength [Mironov and Tuzova, 1980;Krupnik and Saichev, 1981 ]; (2) diffusion theory [lshirnaru, 1978b; Furutsu, 1980a, b; lto, 1984; lshirnaru, 1984] for optical pulsed waves in densely distributed discrete scatterers; (3) multiple scattering theory for waves in media characterized by large-scale discrete inhomogeneities [Svirkunov, 1977;Krutikov, 1979Krutikov, , 1980Lukin, 1981;Diener, 1982; Robeth and Diener, 1983].The motivation for our work is based on the absence of a complete second-order statistical theory for studying pulse propagation through random distributions of correlated scatterers. Such a theory is necessary for the development of predictive models pertinent to (1) pulse electromagnetic wave propagation through complex media (e.g., rain, fog, sand-1037…”
