Playing back recorded audio from digital storage allows us to enjoy music without the physical presence of a musical instrument to generate resonating sound. In a seemingly unrelated area called metamaterials, scientists design different physical structures also resonating with sound or light, to achieve many intriguing phenomena such as negative refraction and invisibility.
Virtualized metamaterial opens door for acoustics application and beyond
