Abstract
Parametric flat lenses, which are an alternative to conventional flat lenses, are described for performing near-field imaging and electronic beam scanning. These lenses can electronically direct the near or far fields, and in some cases even achieve a conversion gain. The lens incorporates a plurality of input and output antennas between which are a plurality of parametric mixers. The parametric mixers can be utilized as well to change phase relationships in accommodating different input pattern or directing the output in different ways. The disclosure also describes a proof of concept implementation using off the shelf components.
