Mid-Infrared Multipole Resonances in Dielectric Metasurfaces with Ultra-High Refractive Indices

We study directional scattering (Kerker effect) in a super-Mossian dielectric
$\text{FeS}_{2}$
. Its refractive index exceeds the traditional Moss rule by 40%. By exciting multipole lattice resonances near the first-diffraction-order Rayleigh anomaly, we observe behavior similar to electric and magnetic dipoles with Kerker condition fulfilled.
