Abstract :
Summary form only given. Characteristic features of beam and pulse interactions with nonlinear dielectric interfaces are discussed. Nonspecular effects of reflection and transmission are defined as deviations of optical signal parameters predicted by geometrical optics. They are caused by a finite beam transverse cross section and a short pulse temporal duration. When the optical signal is described by its second-order moments, the nonspecular effects appear in a form of changes of the beam width, pulse length, direction and speed of propagation, spatial and temporal chirps and on-axis phase and amplitude modifications. Geometrical interpretation of these effects is given and their behaviour at plane boundaries of local and nonlocal nonlinear Kerr dielectrics are presented
