Wigner function for nonparaxial wave fields.
نویسندگان
چکیده
The generalized optical transfer function and the spectral correlation function are investigated for nonparaxial two-dimensional wave fields. The angle-impact marginal of the four-dimensional Wigner function is derived directly. For focused wave fields of semiangle greater than 90 degrees, the spectral correlation function exhibits overlapping and interference. For focused wave fields for which the semiangle is known to be less than 180 degrees, the magnitude and phase can be recovered directly from knowledge of the intensity in the focal region.

Two Methods for Modeling the Propagation of the Coherence and Polarization Properties of Nonparaxial Fields
The propagation of nonparaxial, partially coherent fields may be modeled in many ways. The standard techniques of Huygens-type propagation integrals or plane wave decompositions require quadruple oscillatory integrals that carry a significant computational cost. Two alternative, computationally efficient methods for such modeling are presented here. One uses a discrete nonparaxial basis expansi...
متن کاملNonparaxial shape-preserving Airy beams with Bessel signature.
Spatially accelerating beams that are solutions to Maxwell equations may propagate along incomplete circular trajectories. Taking these truncated Bessel fields to the paraxial limit, some authors have sustained that it has recovered the known Airy beams (AiBs). Based on the angular spectrum representation of optical fields, we demonstrated that the paraxial approximation rigorously leads to off...
متن کاملBehavior of Propagating and Evanescent Components in Azimuthally-polarized Nonparaxial Fields
The contribution of the propagating and the evanescent waves associated with freely propagating nonparaxial light fields whose transverse component is azimuthally polarized at some plane is investigated. Analytic expressions are derived for describing both the spatial shape and the relative weight of the propagating and the evanescent components integrated over the transverse plane. The analysi...
متن کاملDescription of light propagation through a circular aperture using nonparaxial vector diffraction theory.
Using nonparaxial vector diffraction theory derived using the Hertz vector formalism, integral expressions for the electric and magnetic field components of light within and beyond an apertured plane are obtained for an incident plane wave. For linearly polarized light incident on a circular aperture, the integrals for the field components and for the Poynting vector are numerically evaluated. ...
متن کاملKinetics of scalar wave fields in random media
This paper concerns the derivation of kinetic models for high frequency scalar wave fields propagating in random media. The kinetic equations model the propagation in the phase space of the energy density of a wave field or the correlation function of two wave fields propagating in two possibly different media. Dispersive effects due to e.g. spatial and temporal discretizations, which are model...
