Abstract: This paper details a summary review of previously reported work carried out at the Queen’s University of Belfast (UK) into the topic of nonlinear frequency selective surfaces as a means for imaging in the far, or in, the near-field using the principle of phase conjugation. We detail some of the main theoretical and practical issues surrounding this topic. Emphasis is placed on an active dual-sided lens topology based on microwave phase conjugating circuitry and a single layer nonlinearly loaded pumped wire array technology. This paper is intended as a means for rapid assimilation of this topic. It is also hoped that others will wish to expand on the original material which has been created in this area.
Index Terms: phase conjugation, nonlinear frequency selective surface, imaging, spatial data encryption.
