Abstract :
An open 2D phase conjugating surface operating as a negative refraction lens (without the need for metamaterials) and augmented with evanescent field to propagating field converters has been theoretically demonstrated to have sub-wavelength focussing properties. This opens up the way for advanced MIMO applications on restricted size platforms or for fine feature extraction by electromagnetic lensing at distances remotely located from the source objects under investigation.
