An approach for experimental modeling of elementary field cells with heterogeneous polarization is proposed. It is shown that such cells may be obtained by the superposition of orthogonally linearly polarized waves with relatively simple phase surfaces and close intensities. The experimental arrangement for obtaining elementary field cells is suggested. The characteristics of a polarization cell may be easily changed by the change of superposed beam parameters. The results of experimental investigation are presented.
Abstract.Relations for the components of Poynting vector are obtained for quasimonochromatic waves. It is shown that the behaviour of the transverse Poynting vector component is similar to that for the coherent waves. The total angular momentum of the quasi-monochromatic wave can be separated into orbital and spin parts. Using the example of a Gaussian beam, we show that the spin angular momentum is associated with coherence characteristics of the optical beam.
The relations for the components of the Poynting vector of a quasi-monochromatic wave are obtained. It is shown that in this case the behavior of the transversal Poynting component may be defined similarly to that in the coherent case. The total angular momentum of the quasi-monochromatic wave may be divided into the orbital and spin parts. The example of a Gaussian beam shows that the value of the spin angular momentum is connected to the coherence characteristics of the beam. Experimental results are presented.
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.
