Materials’ light tricks may soon extend to doing math

Metamaterials could provide faster pattern recognition

LIGHT MATH  A new simulation shows that a light wave (red squiggle, left) entering into a specially designed structure (cube) can be transformed into the original light wave’s derivative (right), a common computation in calculus.

Tiny structures that use light waves to perform ultrafast complex mathematical operations could be built from available materials, a new computer simulation suggests.
