The study of auxetic materials and mechanical metamaterials has ushered in a new era in materials science, where structural design and geometry enable properties beyond those of conventional materials ...

Electromagnetic, acoustic, and elastic waveguides are commonly used in communication, imaging, and signal isolation to facilitate efficient directional transmission of signals. However, static ...

Until now, designing complex metamaterials with specific mechanical properties required large and costly experimental and simulation datasets. The method enables ...

An international research team has developed mechanical metamaterials with a high elastic energy density. Highly twisted rods that deform helically provide these metamaterials with a high stiffness ...

Materials are usually seen as either soft (like rubber) or hard (like steel). But what if materials could change their stiffness whenever needed—soft for cushioning, stiff for support? Mechanical ...

Mechanical metamaterials research demands interdisciplinary collaboration and innovation. (Nanowerk News) Metamaterials are artificially-structured materials with extraordinary properties not easily ...

Researchers from Universidad Carlos III de Madrid (UC3M) and Harvard University have experimentally demonstrated that new artificial materials known as metamaterials, with magnetic properties, can ...

Why are Metamaterials Unlike Anything in Nature? Material properties are typically defined by electric permittivity (ε) and magnetic permeability (μ), with free space representing the baseline values ...

Metamaterials – artificially made materials with properties that aren’t found in the natural world – are poised to transform daily life. Their unique properties are enhancing products from sporting ...
