A virtual laboratory designed for teaching diffractive lenses

Giménez, F.; Monsoriu, J.A.; Furlan, W.D.; Pons, A. (Universitat Politècnica de València, 2010-06-19)

[EN] We present a virtual laboratory generated in Matlab GuiQc (Graphical User Interface) for its use in Optics courses as an informatic tool for teaching the focusing properties of a diffractive lens. This Gui allows the ...
Análisis Fractal del Control Autonómico del Ritmo Cardiaco durante Oclusión Coronaria

Gomis, Pedro; Caminal, Pere; Vallverdú, Montserrat; Wagner, G. (Universitat Politècnica de València, 2010-01-07)

[ES] El sistema nervioso autónomo a través de sus ramas simpática (de excitación) y parasimpática (de inhibición) regula numerosas variables fisiológicas entre las que se encuentra el ritmo cardiaco. En este trabajo se ...
Fixed point theorems for nonlinear contractions with applications to iterated function systems

Pant, Rajendra (Universitat Politècnica de València, 2018-04-02)

[EN] We introduce a new type of nonlinear contraction and present some fixed point results without using continuity or semi-continuity. Our result complement, extend and generalize a number of fixed point theorems including ...
Fractal square zone plates

Calatayud Calatayud, Arnau; Ferrando Martín, Vicente; Gimenez Palomares, Fernando; Furlan, Walter Daniel; Saavedra, G.; Monsoriu Serra, Juan Antonio (Elsevier, 2013-01-01)

[EN] In this paper we present a novel family of zone plates with a fractal distribution of square zones. The focusing properties of these fractal diffractive lenses coined fractal square zone plates are analytically studied ...
FRACTALES EN LA NATURALEZA.ILUSTRACIÓN Y GEOMETRIA

Vilar Jiménez, Paula (Universitat Politècnica de València, 2023-11-15)

[ES] En el presente trabajo se analiza la relación que existe entre los fractales y la naturaleza y de qué manera se pueden apreciar patrones establecidos partiendo de la observación de elementos naturales vivos. Así ...
Synthesis of fractal light pulses by quasi-direct space-to-time pulse shaping

Monsoriu Serra, Juan Antonio; Mendoza-Yero, O.; Alonso, B.; Minguez-Vega, G.; Sola, I.J.; Lancis, J. (Optical Society of America, 2012)

[EN] We demonstrated a simple diffractive method to map the self-similar structure shown in squared radial coordinate of any set of circularly symmetric fractal plates into self-similar light pulses in the corresponding ...
The world of fractals

Nagy, Peter; Tasnádi, Peter (Editorial Universitat Politècnica de València, 2020-05-04)

[EN] Fractals are fascinating geometric structures of nature which appear in more and more field of science, ranging from heartbeat characterization through, cancer research, stock exchange trends, meteorology, and computer ...
Undergraduate experiment with fractal diffraction gratings

Monsoriu Serra, Juan Antonio; Furlan, Walter D.; Pons, Amparo; Giménez Valentín, Marcos Herminio (European Physical Society, 2011-03-11)

We present a simple diffraction experiment with fractal gratings based on the triadic Cantor set. Diffraction by fractals is proposed as a motivating strategy for students of optics in the potential applications of optical ...
