Relaxed micromorphic broadband scattering for finite-size meta-structures -- a detailed development
Alexios Aivaliotis, Domenico Tallarico, Marco-Valerio D'Agostino +3
The conception of new metamaterials showing unorthodox behaviors with respect to elastic wavepropagation has become possible in recent years thanks to powerful dynamical homogeniza…

Low-and high-frequency Stoneley waves, reflection and transmission at a Cauchy/relaxed micromorphic interface
Alexios Aivaliotis, Ali Daouadji, Gabriele Barbagallo +3
In this paper we study the reflective properties of a 2D interface separating a homogeneous solid from a band-gap metamaterial by modeling it as an interface between a classical Ca…

Relaxed micromorphic model of transient wave propagation in anisotropic band-gap metastructures
Gabriele Barbagallo, Domenico Tallarico, Marco Valerio D'Agostino +3
In this paper, we show that the transient waveforms arising from several localised pulses in a micro-structured material can be reproduced by a corresponding generalised continuum…
