Mechanical mechanisms have been used to process information for millennia, with famous
examples ranging from the Antikythera mechanism of the Ancient Greeks to the analytical …

Phononic crystals (PCs) and metamaterials (MMs) can exhibit abnormal properties, even far
beyond those found in nature, through artificial design of the topology or ordered structure of …

Enhancing vibration isolation with locally resonant metamaterials has attracted wide
attention due to low-frequency band-gap. Moreover, nonlinear periodic structure could …

The study of granular crystals, which are nonlinear metamaterials that consist of closely
packed arrays of particles that interact elastically, is a vibrant area of research that combines …

Elastic metamaterials (EMMs) encompass a relatively new class of composite materials that
exhibit unique dynamic effective material properties and possess the ability to mitigate or …
