Abstract:
Herein it is presented a new vector diffraction integral capable to compute the diffraction patterns for aspheric and freeform wavefronts, with different pupil shapes, and different polarization states. The aforementioned vector diffraction integral is based on the energy conservation theorem, the far field approximation, and the angular spectrum representation of optical fields. The integral is validated through illustrative examples whose results are as expected and coincide with the related works.

Electromagnetic Diffraction in Optical Systems. I. An Integral Representation of the Image Field
TL;DR: In this article, an integral representation for the electromagnetic field in the image space of an optical system is obtained in the form of an angular spectrum of plane waves, which is closely related to that introduced by Luneberg (1944) as a vector generalization of well-known formulae of Debye (1909) and Picht (1925).

Trapping metallic Rayleigh particles with radial polarization
TL;DR: Numerical studies show that optical tweezers using radial polarization can stably trap metallic particles in 3-dimension due to the spatial separation of the gradient force and scattering/absorption forces.

Julius Adams Stratton,L. J. Chu +1 more
TL;DR: In this paper, a vector analog of Green's theorem is applied to the calculation of diffraction of electromagnetic waves from a rectangular slit in a screen of infinite conductivity, and the results are compared with an exact solution obtained recently by Morse and Rubenstein.
