Mie-resonant metaphotonics

Mie-resonant metaphotonics is a rapidly developing field that employs
the physics of Mie resonances to control light at the nanoscale. Mie
resonances are excited in high-refractive-index transparent
nanoparticles and voids created in dielectric media, and they can be
used to achieve a wide range of optical effects, including enhanced
light–matter interaction, nonlinear optical effects, and topological
photonics. Here, we review the recent advances in Mie-resonant
metaphotonics, with a focus on the physics of Mie resonances and their
applications in metaphotonics and metasurfaces. Through a
comprehensive multipolar analysis, we demonstrate the complex
interplay of electric and magnetic multipoles that govern their
interaction with light. Recent advances have unveiled a diverse
spectrum of scattering phenomena that can be achieved within precisely
engineered structures. Within this framework, we review the underlying
mechanics of the first and second Kerker conditions and describe the
intricate mechanisms guiding these nanostructures’ light-scattering
properties. Moreover, we cover intriguing phenomena such as the
anapole and bound or quasi-bound states in the continuum. Of profound
interest are the numerous practical applications that result from
these revelations. Ultrafast processes, the emergence of nanolasers,
and advancements in magneto-optic devices represent just a fraction of
the transformative applications.
