Abstract

The reflection and transmission of a paraxial light beam carrying the spin and intrinsic orbital angular momenta (IOAMs) at a plane interface between two isotropic transparent media is considered. The surface transverse linear momenta (STLMs), i.e., the momenta that are localized near the interface and whose direction is perpendicular to the plane of incidence, are investigated. The IOAM-dependent and spin-dependent STLMs of the beams of homogeneous and inhomogeneous plane waves as well as the interference STLMs in the first medium are calculated. A detailed comparison of these STLMs is made. The way of experimental investigation of STLMs based on the relation between the global STLM and the transverse shift of the center of gravity of the global electromagnetic field is discussed.
