“…Based on Maxwell's equations, we verify our concept by measuring the extinction cross-section and scattering patterns of a spherical particle at the microwave frequency range. To mimic the scattering properties of silicon nanoparticles at microwaves, we use MgO-TiO 2 ceramic spheres characterized by the dielectric constant ε = 16 and dielectric loss factor of about 0.00112, measured in the range 9-12 GHz [31]. A spherical particle with the radius a=7.5 mm is located in a microwave chamber for the measurements in the frequency range 4-10 GHz.…”

All-dielectric resonant nanophotonics lies at the heart of modern optics and nanotechnology due to the unique possibilities to control scattering of light from high-index dielectric nanoparticles and metasurfaces. One of the important concepts of dielectric Mie-resonant nanophotonics is associated with the Kerker effect that drives the unidirectional scattering of light from nanoantennas and Huygens' metasurfaces. Here we suggest and demonstrate experimentally a novel effect manifested in the nearly complete simultaneous suppression of both forward and backward scattered fields. This effect is governed by the Fano interference between an electric dipole and off-resonant quadrupoles, providing necessary phases and amplitudes of the scattered fields to achieve the transverse scattering. We extend this concept to dielectric metasurfaces that demonstrate zero reflection with transverse scattering and strong field enhancement for resonant light filtering, nonlinear effects, and sensing.
