Owing to the versatility and the capabilities of metasurfaces, many exotic and peculiar optical phenomena ranging from negative refraction, sub-diffraction optical microscopy, and broad band achromatic lenses have been demonstrated recently. Most of these designs have been engineered by doing large and costly parametric search to obtain the optical response of individual building blocks. Remarkably, complex designs such as broadband and multiplexed interfaces exclusively rely on sub-units of near-field coupled antennas to achieve the required scattering responses. The inherent complexity of the latter designs result in poorly efficient components, indicating that the stringent design and fabrication requirements are failing to achieve designs of realistic imaging devices. |
