Extreme Wave Manipulation with Parity-Time Symmetric Metasurfaces

We study the unique wave manipulation capabilities of Parity-Time symmetric pairs of metasurfaces operated at exceptional point conditions. We demonstrate theoretically and experimentally the relevance of these systems to induce wave phenomena typically observed with bulk metamaterials, including negative refraction, planar focusing, or cloaking, while avoiding their typical drawbacks, like sensitivity to losses, imperfect isotropy, and fabrication complexity. We discuss the relations between bandwidth and stability, demonstrating the practical potential of these systems for controlling waves in unprecedented ways.
