Lower bound of group velocity imposed by non-linearities induced by external sources in photonic and phononic crystals with losses

Escalante, José M. (IOP Publishing, 2024-02-01)

[EN] In the present work, it has been studied how the group velocity, in waves propagating trough photonic and phonic crystals with losses, is affected by non-linearities induced by external sources. The work takes as ...
Nonlinear propagation and control of acoustic waves in phononic superlattices

Jimenez, Noe; Mehrem, Ahmed; Picó Vila, Rubén; García-Raffi, L. M.; Sánchez Morcillo, Víctor José (Elsevier Masson, 2016-05)

The propagation of intense acoustic waves in a one-dimensional phononic crystal is studied. The medium consists in a structured fluid, formed by a periodic array of fluid layers with alternating linear acoustic properties ...
Towards the full control of sound with sonic crystals and acoustic metamaterials

Torrent Martí, Daniel (Universitat Politècnica de València, 2008-09-12)

El objetivo de este trabajo ha sido obtener expresiones matemáticas para los parámetros elásticos y acústicos efectivos de sistemas heterogéneos en el límite de homogeneización, lo que ha permitido el diseño de nuevos ...
