Scattering engineering: From broadband cloaking and resonance effects, to embedded scattering eigenvalues in 3D nanostructures

Abstract

Invisibility, resonant scattering and light trapping are among the most intriguing optical phenomena. Here, we show that these seemingly unrelated effects are tightly connected and can be tailored by suitably engineering the scattering response of composite nanoparticles. We demonstrate broadband cloaking and resonance effects, as well as embedded scattering eigenstates with infinite lifetime.
