A Lyapunov inequality for a second order nonlinear differential equation

Almenar, P.; Jódar Sánchez, Lucas Antonio (Elsevier, 2011-04)

This paper presents a Lyapunov-type inequality for the second order nonlinear equation (r(x)y')' + p(x)f(y(x)) = 0, with r(x), p(x) > 0 and f(y) odd and positive for y > O. It also compares it with similar results. (C) ...
Analysis of equivalent anisotropy arising from dual isotropic layers of acoustic media

Cai, Liang-Wu; Sánchez-Dehesa Moreno-Cid, José (Acoustical Society of America, 2012-10)

The equivalence between a single mass-anisotropic layer and two isotropic layers is analyzed by studying two systems: one consists of an anisotropic layer sandwiched between two arbitrarily chosen isotropic media; and the ...
Asymptotic behaviour of the solutions of second order functional differential equations

Almenar, Pedro; Jódar Sánchez, Lucas Antonio (Elsevier, 2011-07)

This paper presents integral criteria to determine the asymptotic behaviour of the solutions of second order nonlinear differential equations of the type y¿(x)+q(x)f(y(x))=0, with q(x)>0 and f(y) odd and positive for y>0, ...
Low-Loss multilayered metamaterial exhibiting a negative index of refraction at visible wavelengths

García Meca, Carlos; Hurtado Montañés, Juan; Martí Sendra, Javier; Martínez Abietar, Alejandro José; Dickson, Wayne; Zayats, Anatoly V. (American Physical Society, 2011-02-11)

We experimentally demonstrate a low-loss multilayered metamaterial exhibiting a double-negative refractive index in the visible spectral range. To this end, we exploit a second-order magnetic resonance of the so-called ...
New efficient numerical methods to describe the heat transfer in a solid medium

Ponsoda Miralles, Enrique; Blanes Zamora, Sergio; Bader, Philipp (Elsevier, 2011-10)

The analysis of heat conduction through a solid with heat generation leads to a linear matrix differential equation with separated boundary conditions. We present a symmetric second order exponential integrator for the ...
