Fernández Álvarez-Estrada, Ramón ; Calvo Padilla, María Luisa | American Institute of Physics | 1980The scattering of electromagnetic waves by an infinite dielectric cylinder with variable dielectric permeability presents, in general, certain mathematical difficulties regarding the construction of rigorous solutions. We give a new divergencele[...]texto impreso
Kundikova, Nataliya D. ; Ryzhkova, A. V. ; Alieva, Tatiana Krasheninnikova ; Calvo Padilla, María Luisa ; Rodrigo Martín-Romo, José Augusto | Maik Nauka, Interperiodica, Springer-Verlag | 2008-05The effect of the Gaussian beam width on the focusing properties of the chainlike Gaussian beam formed upon diffraction of laser radiation on a binary amplitude mask is studied. It is found that a decrease in the Gaussian beam width increases th[...]texto impreso
Martínez Matos, Óscar ; Calvo Padilla, María Luisa ; Cheben, Pavel ; Monte Muñoz de la Peña, Francisco del ; Rodrigo Martín-Romo, José Augusto | American Physical Society | 2006-08-25We report observations of periodic oscillatory behavior of the angular selectivity, near the Bragg angle, in volume holographic gratings recorded in a new photopolymerizable glass with high refractive index modulation. We have detected the prese[...]texto impreso
Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova ; Calvo Padilla, María Luisa | Optical Society of America | 2007-10The gyrator transform (GT) promises to be a useful tool in image processing, holography, beam characterization, mode transformation, and quantum information. We introduce what we believe to be the first flexible optical experimental setup that p[...]texto impreso
The multiple scattering of classical electromagnetic waves byN fixed dielectric obstacles is studied by using a new Green’s function introduced in a previous paper. The use of the new Green’s function leads us to show that the kernels of the bas[...]texto impreso
Martínez Matos, Óscar ; Hernández Garay, María de la Paz ; Izquierdo, J. G. ; Vaveliuk, Pablo ; Bañares Morcillo, Luis ; Calvo Padilla, María Luisa | American Institute of Physics | 2014-07-28A procedure to characterize the induced damage and the incubation effects in volume transmission gratings under femtosecond laser pulse train illumination is presented. It was also developed a formalism that explains the damage processes. Our pr[...]texto impreso
Martínez Matos, Óscar ; Hernández Garay, María de la Paz ; González Izquierdo, Jesús ; Calvo Padilla, María Luisa ; Vaveliuk, Pablo ; Cheben, Pavel ; Bañares Morcillo, Luis | Optical Society of America | 2011-01-17The majority of the applications of ultrashort laser pulses require a control of its spectral bandwidth. In this paper we show the capability of volume phase holographic gratings recorded in photopolymerizable glasses for spectral pulse reshapin[...]texto impreso
Guibelalde del Castillo, Eduardo ; Calvo Padilla, María Luisa | The Optical Society Of America | 1982We present a theoretical model for the filter function of a holographic grating when the absorption coefficient of the photomaterial is nonnegligable. In this case there is also modulation in the conductivity, which leads to a cosinusoidal funct[...]texto impreso
Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova ; Calvo Padilla, María Luisa | American Institute of Physics (AIP) | 2006In this work we propose a flexible symmetric configuration for the separable fractional FT composed by three generalized lenses. The distances between the lenses are fixed. The fractional angles are acieved by means of lens rotations.texto impreso
Molina de la Peña, Ignacio ; Calvo Padilla, María Luisa ; Álvarez Estrada, Ramón F. | Taylor & Francis Ltd | 2019-06-22We studied the propagation of slow neutrons and their waveguiding properties in certain suitable thin films where Ti and Si play a key role, having in mind their possible use in Boron Neutron Capture Therapy (BNCT) of small tumors. In PBSi2017 w[...]texto impreso
Calvo Padilla, María Luisa ; Alieva, Tatiana Krasheninnikova ; Bastiaans, Martin J. ; Rodrigo Martín-Romo, José Augusto ; Rodríguez Merlo, D. | SPIE--The International Society for Optical Engineering | 2004We present a short overview on the application of fractional cyclic and linear canonical transformations to optical signal processing and dedicate some of the discussions to the particular features found in the fractional Fourier transform domain.texto impreso
Davis, Jeffrey A. ; Ramirez, Laura ; Rodrigo Martín-Romo, José Augusto ; Alieva, Tatiana Krasheninnikova ; Calvo Padilla, María Luisa | Alan E. Willner, University of Southern California | 2004-06-15We report the first experimental results, to our knowledge, with fractal zone plates implemented in a liquid-crystal display. Our results largely agree with theory for the axial irradiance distribution of these lenses. The dependence of the shap[...]texto impreso
Davis, Jeffrey A. ; Sigarlaki, Sean Paul ; Craven, Julia M. ; Calvo Padilla, María Luisa | The Optical Society Of America | 2006-02-20We report on a Fourier series approach that predicts the focal points and intensities produced by fractal zone plate lenses. This approach allows us to separate the effects of the fractal order from those of the lens aperture. We implement these[...]texto impreso
Bastiaans, Martin J. ; Alieva, Tatiana Krasheninnikova ; Calvo Padilla, María Luisa | Hindawi Publishing Corporation | 2005-07-01We review the progress achieved in optical information processing during the last decade by applying fractional linear integral transforms. The fractional Fourier transform and its applications for phase retrieval, beam characterization, space-v[...]texto impreso
In this study the general algorithm for the fractionalization of the linear cyclic integral transforms is established. It is shown that there are an infinite number of continuous fractional transforms related to a given cyclic integral transform[...]
