Collective lattice resonances in disordered and quasi-random all-dielectric metasurfaces [Текст] / Вадим Игоревич Закомирный, Сергей Васильевич Карпов, Огрен Ханс, Илья Леонидович Рассказов // Journal of the Optical Society of America B. — 2019. — Т. 36 (№ 7). — С. 21-29Аннотация:
Collective lattice resonances in disordered 2D arrays of spherical Si nanoparticles (NPs) have been thoroughly studied within the framework of the coupled dipole approximation. Three types of defects have
been analyzed: positional disorder, size disorder, and quasi-random disorder. We show that the positional disorder strongly suppresses either the electric dipole (ED) or the magnetic dipole (MD) coupling
depending on the axis along which the NPs are shifted. Contrary, size disorder strongly affects only the
MD response, while the the ED resonance can be almost intact, depending on the lattice configuration.
Finally, random removing of NPs from an ordered 2D lattice reveals a quite surprising result: hybridization of the ED and MD resonances with lattice modes remains observable even in the case of random
removing of up to 84% of the NPs from the ordered array. Reported results could be important for rational design and utilization of metasurfaces, solar cells and other all-dielectric photonic devices
