Suspensions of microparticles dispersed in air or liquids are useful for designing media with desirable optical extinction properties within the visible or infrared spectrum. We describe here a numerical iterative optimization algorithm used to design multilayered concentric dielectric spheres with prescribed optical scattering properties. Our method integrates a computationally efficient rigorous electromagnetic solver, based on Mie theory, within an optimization loop to determine specific particle configurations that best meet a desired optical response. In particular, we show that this method can be used to design all-dielectric spherical particles that possess narrow tunable transparency windows while removing any angular dependency on the optical response.
