Nonlinear surface waves in left-handed materials.
We study both linear and nonlinear surface waves localized at the interface separating a left-handed (LH) medium (i.e., a medium with both negative dielectric permittivity and negative magnetic permeability) and a conventional [or right-handed (RH)] dielectric medium. We demonstrate that the interface can support both TE- and TM-polarized surface waves-surface polaritons, and we study their pro...
متن کاملNonlinear transverse waves in deformed dispersive solids
We present a phenomenological approach to dispersion in nonlinear elasticity. A simple, thermomechanically sound, constitutive model is proposed to describe the (non-dissipative) properties of a hyperelastic dispersive solid, without recourse to a microstructure or a special geometry. As a result, nonlinear and dispersive waves can travel in the bulk of such solids, and special waves emerge, so...
متن کاملUltra-Fast Diffusion in Severely Deformed Materials
1. Introduction Severe plastic deformation (SPD) is nowadays used to produce sizeable amounts of bulk nanocrystalline materials, which renders them suitable for different innovative applications, owing to favourable combinations of high mechanical strength and enhanced ductility they offer. Enhanced grain boundary diffusion is largely responsible for the resulting property combinations. SPD pro...
متن کاملGiant Gravitons on Deformed PP-waves
The recently constructed Lunin-Maldacena deformation of AdS5 ×S5 is known to support two inequivalent Penrose limits that lead to BPS pp-wave geometries. In this note, we construct new giant graviton solutions on these backgrounds. A detailed study of the spectra of small fluctuations about these solutions reveals a remarkably rich structure. In particular, the giants that we contruct fall into...
متن کاملAcceleration Waves in Complex Materials
A framework for modeling acceleration waves propagation in complex materials is presented. Coupled propagation of elasto-acoustic, microstructural and thermal waves is investigated in the full three dimensional case. The presence of microstructure inside each material element is taken into account without introducing additional hypotheses on the physical nature of the microstructure itself, thu...
