Abstract:We present in this work a study of the diffraction of a focused Gaussian beam by a microrefractive cylinder, and the dependence of the far field diffracted pattern with the location of the beam focal plane, relative to the center of the cylinder. A numerical study of the problem is carried out and validated with experimental verification. We center our attention on two parameters: the divergence and the number of peaks of the diffracted field. Both present a minimum for a particular position of the focal plane… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
