Metamaterials have the ability to create an effect based on their structure. Most metamaterials in recent news have involved optical or electrical effects. Researchers at the Universities of Sussex and Bristol have invented metamaterials that bend, shape, and focus sound. This has potential applications in medical imaging, sonar, haptics, and personal audio.

A super-material that bends, shapes and focuses sound waves that pass through it has been invented by scientists.
The creation pushes the boundaries of metamaterials – a new class of finely-engineered surfaces that perform nature-defying tasks.
These materials 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 research team from the Universities of Sussex and Bristol have now shown that they also work with sound waves, which could transform medical imaging and personal audio.
