Abstract

We numerically demonstrate selective absorption of visible light in film-coupled nanoparticle metamaterials by excitation of magnetic resonance. The physical mechanism of magnetic resonance is elucidated with the help of electromagnetic field distribution. Resonance wavelengths are shown to be strongly dependent on geometric parameters. Representative inductor-capacitor models are employed to further confirm the underlying mechanism and explain the unique behaviors of magnetic resonance in film-coupled nanoparticle metamaterials.
