Metamaterials and the new rules of refraction

Written by

$Zanotto and Pitanti are developing metamaterials, a new type of material for the manipulation of optical and mechanical waves through negative refraction$

Waves are amazing things. We use light waves for telecommunications applications and make use of mechanical waves for everything from musical instruments to sensing. Being able to control and use waves, though, relies on components to manipulate their properties. Drs Simone Zanotto and Alessandro Pitanti at the CNR – Istituto di Nanoscienze in Pisa, Italy, are now developing a new […]
