1. Metamaterial bricks are assembled into a layer to produce a meta-surface, which could have applications across healthcare and entertainment
2, These space coiling bricks act to slow down sound waves, meaning that they can be transformed into any required sound field.
A super-material that bends, shapes and focuses sound waves that pass through it has been invented by scientists. Metamaterials have already shown remarkable results with light manipulation, allowing scientists to create a real-life version of Harry Potter’s invisibility cloak, for example. But a Universities of Sussex and Bristol team have now shown that they also work with sound waves, which could transform medical imaging and personal audio.
Finely shaped sound fields are used in medical imaging and therapy as well as in ...
