Non-Paraxial Electromagnetic Beams

Proposals for the generation of angular momentum from non-uniformly polarized beams

“…In this paper we propose different arrangements to endow a beam with global spin and/or global orbital angular moment by using uniformly and non uniformly polarized beams [20]. In order to synthesize this type of fields the use of some devices such as unconventional polarizers and polarization converters is proposed.…”
