Effective mass density for wave propagation in periodic layered media in the elasto-acoustic transition
Gabriel Núñez, William J. Parnell, Raphaël C. Assier
This article investigates the effective mass density for acoustic and elastic wave propagation in layered media, with emphasis on its transition between these regimes. Conventional…
Waves within a network of slowly time-modulated interfaces: time-dependent effective properties, reciprocity and high-order dispersion
Michaël Darche, Raphaël Assier, Sébastien Guenneau +2
We consider wave propagation through a 1D periodic network of slowly time-modulated interfaces. Each interface is modelled by time-dependent spring-mass jump conditions, where mass…
Wave scattering by a transversal defect in a discrete waveguide
Elena Medvedeva, Raphael Assier, Anastasia Kisil
We study wave scattering by a finite transversal strip in a discrete square-lattice waveguide with Dirichlet boundary conditions imposed on the strip and the waveguide walls. The s…
