Near-field scanning optical microscopy or scanning near-field optical microscopy is a microscopy technique for nanostructure investigation that breaks the far field resolution limit by exploiting the properties of evanescent waves.

a set of communication protocols that enables communication between two electronic devices over a distance of or less.

A near-field magnetic induction communication system is a short range wireless physical layer that communicates by coupling a tight, low-power, non-propagating magnetic field between devices.
