Architected metamaterials offering superior dynamic performances can be conceived by
inducing local mechanisms of inertia amplification in the periodic microstructure. A one …

Microstructured materials, namely metamaterials, are one of the most relevant topics of the
recent period due to their interdisciplinary nature. Driven by their wide range of applications …

The paper addresses an important issue of cloaking transformations for fourth-order partial
differential equations representing flexural waves in thin elastic plates. It is shown that, in …

Based on rigorous theoretical findings, we present a proof-of-concept design for a structured
square cloak enclosing a void in an elastic lattice. We implement high-precision fabrication …

In this paper, we propose an innovative design of an elastic network, which is capable of
channelling the energy supplied by an external source towards any of its endpoints, that can …

The free propagation of acoustic plane waves through cellular periodic materials is
generally accompanied by a flow of mechanical energy across the adjacent cells. The paper …

It is known that design of elastic cloaks is much more challenging than that of acoustic
cloaks, cloaks of electromagnetic waves or scalar problems of anti-plane shear. In this …

We address the scattering and transmission of a plane flexural wave through a semi-infinite
array of point scatterers/resonators, which take a variety of physically interesting forms. The …

Phononic crystals and acoustic metamaterials have unique properties, such as the existence
of band gaps, which give them huge potential in many applications, such as vibration …

In elasticity, the design of a cloaking for an inclusion or a void to leave a vibrational field
unperturbed by its presence, so to achieve its invisibility, is a thoroughly analysed, but still …
