Title: | Multipole theory for tight focusing of polarized light, including radially polarized and other special cases | Authors: | Hoang, T.X. Chen, X. Sheppard, C.J.R. |
Issue Date: | 1-Jan-2012 | Citation: | Hoang, T.X.,Chen, X.,Sheppard, C.J.R. (2012-01-01). Multipole theory for tight focusing of polarized light, including radially polarized and other special cases. Journal of the Optical Society of America A: Optics and Image Science, and Vision 29 (1) : 32-43. ScholarBank@NUS Repository. | Abstract: | A multipole expansion, based on spherical harmonics, provides an efficient method for calculating the field in the focal region of a lens for radially polarized illumination, or other illumination polarization and phase distributions, including vortex beams. The multipole approach also has the benefit of providing a simple measure of the purity of the longitudinal field mode. The method is also convenient for calculation of fields scattered by particles and calculation of optical trapping forces. © 2011 Optical Society of America. | Source Title: | Journal of the Optical Society of America A: Optics and Image Science, and Vision | URI: | http://scholarbank.nus.edu.sg/handle/10635/50987 | ISSN: | 10847529 |
