Efficient integral equation approach for metamaterials made of core-shell nanoparticles at optical frequencies

摘要

This study exploits the surface equivalence principle to obtain a reduced system of equations for a problem that includes doubly periodic infinite arrays of multi-layers of core-shell nanoparticles, illuminated by a plane wave, above a dielectric substrate. The proposed approach allows a different host medium for each layer of nanoparticles without employing multilayered media Green's function.
