Abstract

Metamaterials enable precise tailoring of light–matter interactions at the subwavelength scale, permitting access to the full range of electromagnetic responses encoded in Maxwell’s equations and operating across a huge swath of the electromagnetic spectrum. These salient features have, during the past two decades, fuelled fundamental metamaterials research which, in turn, has unveiled an impressive assemblage of potential applications. Imaging is at the forefront of these developments, leveraging the ability of metamaterials to achieve arbitrary, specific and tunable scattering responses that are poised for integration with a host of materials and devices. We review the impact of metamaterials and metasurface on imaging science and technology from microwave to optical frequencies. Our focus is on metamaterial-based imaging components and the associated imaging modalities that benefit from these advances.
