A negative reflective/refractive "meta-interface" using a bi-directional phase-conjugating array

A negative reflective/refractive "meta-interface" using a bi-directional phase-conjugating antenna array is proposed. Negative reflection is due to the retro-directivity of the array while negative refraction is a consequence of the bi-directionality of the slot elements used in the array. A simple design of the interface is presented. The prototype demonstrates negative reflection and refraction in far-field and near-field measurements.
