    Abstract

    The original Kerker e ect was introduced for a hypothetical magnetic sphere, and initially it did not attract much attention due to a lack of magnetic materials required. Rejuvenated by the recent explosive development of the field of metamaterials and especially its core concept of optically-induced artificial magnetism, the Kerker e ect has gained an unprecedented impetus and rapidly pervaded di erent branches of nanophotonics. At the same time, the concept behind the e ect itself has also been significantly expanded and generalized. Here we review the physics and various manifestations of the generalized Kerker e ects, including the progress in the emerging field of meta-optics that focuses on interferences of electromagnetic multipoles of di erent orders and origins. We discuss not only the scattering by individual particles and particle clusters, but also the manipulation of reflection, transmission, di raction, and absorption for metalattices and metasurfaces, revealing how various optical phenomena observed recently are all ubiquitously related to the Kerker’s concept.
