Systems and methods for imaging a distant light source at an enhanced resolution is provided. An evanescent field generator an evanescent field generator that receives an incident electromagnetic field representing at least one distant light source and restores high spatial frequency components to the incident electromagnetic field, resulting in an evanescent field. A negative refractive index lens assembly focuses the evanescent field onto a focal plane. A photodetector assembly located in the focal plane detects the focused evanescent field as an image of the at least one distant light source.

Imaging system using a negative index of refraction lens

Systems and methods for reducing the beamwidth of an antenna system are provided. An evanescent field generator generates an evanescent field representing a far field radio frequency (RF) signal received at the antenna system. A negative refractive index lens assembly focuses the evanescent field onto a focal plane. An RF detector assembly located in the focal plane detects the amplified evanescent field.
