Stabilization of volume gratings recorded in polyvinyl alcohol-acrylamide photopolymers with diffraction efficiencies higher than 90%
Gallego Rico, Sergi - Neipp López, Cristian - Ortuño Sánchez, Manuel - Beléndez Vázquez, Augusto - Pascual Villalobos, Inmaculada

Formato:	info:eu-repo/semantics/article
Enlaces:	Obtaining holographic volume gratings with high diffraction efficiencies that can be used under white light has been a serious problem for the polyvinyl alcohol-acrylamide-based photopolymers developed by other researchers. In this paper we propose to eliminate the residual monomer in…

Analytical approximate solutions for the cubic-quintic Duffing oscillator in terms of elementary functions
Beléndez Vázquez, Augusto - Álvarez López, Mariela Lázara - Francés Monllor, Jorge - Bleda Pérez, Sergio - Beléndez Vázquez, Tarsicio - Nájera López, Alberto - Arribas Garde, Enrique

Formato:	info:eu-repo/semantics/article
Enlaces:	Accurate approximate closed-form solutions for the cubic-quintic Duffing oscillator are obtained in terms of elementary functions. To do this, we use the previous results obtained using a cubication method in which the restoring force is expanded in Chebyshev polynomials and…
