They show considerable potential in many applications, including vibration insulation, wave-guiding, noise control, and energy harvesting technologies. While the foundation of metamaterials research ...

Metamaterials are artificial materials comprised of an array of nanostructures, which serve as the building blocks, or "meta-atoms." Unlike natural materials, the properties of metamaterials are not ...

Could invisibility cloaks become a reality? New research brings this science fiction concept a step closer, with a breakthrough software package that simulates how waves interact with complex ...

Given a 3D piece of origami, can you flatten it without damaging it? Just by looking at the design, the answer is hard to predict, because each and every fold in the design has to be compatible with ...

Topological insulators (TIs) have fundamentally reshaped our understanding of materials by introducing robust boundary states arising from bulk topological invariants. Extending this paradigm, ...

This will vastly improve the ability to rapidly design metamaterials – exciting artificial materials used to amplify, block or deflect waves. The findings, published in the journal Proceedings of the ...

This image is a simulation of a kind of acoustic wave called a Rayleigh-Bloch wave. The stripes of light and dark areas represent the “peaks" and “troughs" of the waves and are shaped by their ...
