Scientists at the University of Birmingham have designed a lens using metamaterials that can function as a convex or a concave lens, according to research published in the journal Nature Communications. By fabricating gold nano-rods on the glass, this new lens can magnify or demagnify objects, just by switching the polarisation of the light source.
