However, the use of these devices with highly convergent field poses a practical problem because the non transversal character of electric field. In this article, we discuss the behavior of highly focused beams with spiral polarization when they pass through a polarizer. Interestingly, beams with azimuthal polarization display a non negligible irradiance in the direction of propagation after passing through a polarizer. On top of that, we found that the irradiance of a highly focused radially polarized beam after a polarizer is notably different from the projection of the field on the direction of the polarizer axis.11 p.application/pdfengcc-by-nc-nd (c) Elsevier, 2017http://creativecommons.org/licenses/by-nc-nd/3.0/esPolarització (Llum)Òptica físicaPolarization (Light)Physical opticsinfo:eu-repo/semantics/article6727682017-11-30info:eu-repo/semantics/openAccess
