A new lens on the world: Improving the metalens with liquid crystal

Physicists have taken a step toward making 'metalenses' even more useful -- by making them reconfigurable. They did this by harnessing nanoscale forces to infiltrate liquid crystals between those microscopic pillars, allowing them to shape and diffract the light in completely new ways -- 'tuning' the focusing power, one of the researchers said.
