Nano World: Nanoantennas superfocus light
Charles Q. Choi: Antennas made of gold strips only nanometers wide can focus light far more precisely than any existing lens, experts told UPI's Nano World.
The nanoantennas could lead to advanced optical telecommunications systems, microscopes that can image proteins, secure computer networks that can instantly detect eavesdroppers, and more efficient optical data-storage devices.
