We analyze the paraxial beam transformation upon reflection and refraction at a plane boundary. In contrast to the usual approach dealing with the beam angular spectrum, we apply the continuity conditions to explicit spatial representations of the electric and magnetic fields on both sides of the boundary. It is shown that the polarization-dependent distortions of the beam trajectory (in particular, the "longitudinal" Goos-H\"anchen shift and the "lateral" Imbert-Fedorov shift of the beam… 
Spin-orbit interaction of light and diffraction of polarized beams
The edge diffraction of a homogeneously polarized light beam is studied theoretically based on the paraxial optics and Fresnel-Kirchhoff approximation, and the dependence of the diffracted beam
Transverse forces related to the transverse shifts of reflected and transmitted light beams
The process of reflection and transmission of a paraxial wavepacket at a plane interface of two isotropic transparent media is considered. The transverse force (TF), i.e., the force perpendicular to
Goos–Hänchen and Imbert–Fedorov beam shifts: an overview
We consider reflection and transmission of polarized paraxial light beams at a plane dielectric interface. The field transformations taking into account a finite beam width are described based on the
Relevance of longitudinal fields of paraxial optical vortices
Longitudinal electromagnetic fields generally become comparable with the usually dominant transverse components in strongly focused, non-paraxial beams. For paraxial optical vortex modes it is
Dynamical characteristics of Laguerre–Gaussian vortex beams upon reflection and refraction
Laguerre–Gaussian beams with vortex structure, as a special type of electromagnetic wave, can carry energy, momentum, and angular momentum, which is crucial for understanding of dynamical processes
Incident-polarization-sensitive and large in-plane-photonic-spin-splitting at the Brewster angle.
This Letter reports a phenomenon of large in-plane-photonic-spin-splitting (IPPSS) in the case of a linear polarized Gaussian light beam reflected from an air-glass interface at the Brewster angle, which is quite larger than the previously reported value.

Focused linearly-polarized-light scattering from a silver nanowire: Experimental characterization of the optical spin-Hall effect
Spin-orbit interactions (SOIs) are a set of subwavelength optical phenomena in which spin and spatial degrees of freedom of light are intrinsically coupled. One of the unique examples of a SOI, the
Conservation of the spin and orbital angular momenta in electromagnetism
We review and re-examine the description and separation of the spin and orbital angular momenta (AM) of an electromagnetic field in free space. While the spin and orbital AM of light are not

The main idea of this review is to trace the interrelations and inter-transitions between the basic concepts and approaches of the correlation optics (including the light coherence) and the singular


Improved theory for the polarization-dependent transverse shift of a paraxial light beam in free space
Spatial distribution of the longitudinal field component of a circularly polarized optical beam depends on the polarization handedness, which causes the lateral shift of the beam "center of gravity"

These observations agree well with numerical calculations based on an angular spectral analysis and are attributable to the helical wavefront of the LG beams, the sharp incidence-angle dependence of the Fresnel reflection and transmission coefficients, and the Gouy phase.
