Suárez Bermejo, J. C. ; González de Sande, Juan Carlos ; Santarsiero, Massimo ; Piquero Sanz, Gemma María | IEEE | 2019The main error sources of a recently proposed Mueller matrix polarimetric method based on the use of full Poincare beams (FPBs) are described and analysed in detail. Numerical simulations are performed under the presence of different sources of [...]texto impreso
Martínez Herrero, Rosario ; Piquero Sanz, Gemma María ; González de Sande, Juan Carlos ; Santarsiero, Massimo ; Gori, Franco | MDPI | 2019-07-01Partially coherent sources with non-conventional coherence properties present unusual behaviors during propagation, which have potential application in fields like optical trapping and microscopy. Recently, partially coherent sources exhibiting [...]texto impreso
Piquero Sanz, Gemma María ; Santarsiero, Massimo ; Gori, Franco ; González de Sande, Juan Carlos | IOP Publishing, Ltd. | 2013-05Planar electromagnetic sources characterized by a periodic variation of their beam coherence-polarization matrix are investigated, as far as the polarization features of the radiated fields are concerned, within the framework of the paraxial app[...]texto impreso
González de Sande, Juan Carlos ; Santarsiero, Massimo ; Gori, Franco ; Piquero Sanz, Gemma María | Optical Society of America | 2014-04-01Generally speaking, the difference between two cross-spectral densities (CSDs) does not represent a correlation function. We will furnish a sufficient condition so that such difference be a valid CSD. Using such a condition, we will show through[...]texto impreso
González de Sande, Juan Carlos | Universidad Complutense de Madrid, Servicio de Publicaciones | 1994-05-16En estos trabajos se ha medido el efecto nernst-ettingshausen en muestras policristalinas de bismuto y a partir de su estudio se han determinado los tiempos de relajación de los distintos portadores, sus masas efectivas y sus potenciales químico[...]texto impreso
González de Sande, Juan Carlos ; Santarsiero, Massimo ; Piquero Sanz, Gemma María | Spie-Int Soc Optical Engineering | 2017The generation of non-uniformly totally polarized beams and the study of their applications is a subject of increasing interest in the last years. A particular class of beams of this kind are the so-called full Poincare beams, which have the pro[...]texto impreso
González de Sande, Juan Carlos ; Piquero Sanz, Gemma María ; Santarsiero, Massimo | Scitepress | 2017A simple method for Mueller matrix polarimetry is proposed. The experimental set up is based on using an azimuthally polarized input beam, which presents all possible linearly polarized states across its transverse section, and an adapted commer[...]texto impreso
Piquero Sanz, Gemma María ; González de Sande, Juan Carlos ; Santarsiero, Massimo ; Gori, Franco | IOP Publishing, Ltd. | 2014-03The irradiance and polarization characteristics of quasi-monochromatic partially coherent electromagnetic beams are analyzed when they propagate after passing through a deterministic linear optical element, i.e., an optical element that can be r[...]texto impreso
González de Sande, Juan Carlos ; Martínez Herrero, Rosario ; Piquero Sanz, Gemma María ; Maluenda, David | Scitepress | 2017A new model of physically realizable electromagnetic source is proposed. The source is partially coherent and non-uniformly totally polarized. The coherence and polarization characteristics of this new source are analyzed. The spatial coherence [...]texto impreso
Piquero Sanz, Gemma María ; Santarsiero, Massimo ; Martínez-Herrero, M. ; González de Sande, Juan Carlos ; Alonzo, M. ; Gori, F. | Optical Society of America | 2018-05-15Partially coherent sources with radial coherence are proposed. They present a circularly symmetric intensity profile and a degree of coherence whose absolute value only depends on the angular difference between the two considered points. In part[...]texto impreso
Martínez Herrero, Rosario ; Maluenda, David ; Piquero Sanz, Gemma María ; González de Sande, Juan Carlos ; Santarsiero, Massimo ; Gori, Franco | Spie-Int Soc Optical Engineering | 2017In this work a new type of partially polarized and partially coherent sources is proposed. The coherence characteristics of these sources are dependent on the difference of the radial distances from the source center of the two points to be comp[...]texto impreso
González de Sande, Juan Carlos ; Piquero Sanz, Gemma María ; Santarsiero, Massimo | Elsevier Science B.V. | 2018-03-01Nonuniformly polarized light can be used for Mueller polarimetry of homogeneous linear samples. In this work, a set up based on using azimuthally polarized input light and a modified commercial light polarimeter is proposed and developed. With t[...]texto impreso
The propagation of partially coherent and partially polarized beams after a linear deterministic periodic structure is investigated. Spatial irradiance, degree of polarization and state of polarization across the transverse plane are obtained at[...]texto impreso
Piquero Sanz, Gemma María ; Monroy, L. ; Santarsiero, M. ; Alonzo, M. ; González de Sande, Juan Carlos | IOP Publishing, Ltd. | 2018-06A simple optical system is proposed to generate full-Poincare beams (FPBs), i.e. beams presenting all possible states of (total) polarization across their transverse section. The method consists in focusing a uniformly polarized laser beam onto [...]texto impreso
González de Sande, Juan Carlos ; Santarsiero, Massimo ; Piquero Sanz, Gemma María ; Gori, Franco | IOP Publishing | 2015-12Using recently derived results about the difference of two cross-spectral densities, we consider a source whose correlation function is the difference of two mutually displaced Gaussian Schell-model cross-spectral densities. We examine the main [...]
