Wave propagation in disordered media

This paper gives a brief overview of the physics of waves in random media. It begins by reviewing some of the basics of wave physics and then discusse s waves in situations of increasing randomness, beginning with scintillatio n of light passing through an inhomogeneous medium, photon scattering and d iffusion, stochastic wave amplification, Anderson localization of waves in random media, and nonlinear wave physics where waves induce randomness in t he medium. A number of physical examples of each phenomenon are discussed t o illustrate the physics and demonstrate the practical importance of the ef fects considered.
