    Abstract

    We propose metamaterial super absorbers that efficiently absorb incoming radiation over an operational bandwidth ranging from 0.20-5.99 μm with an integrated absorption as high as 97.1%. A periodic array of pyramidal metal-dielectric (Au/Si) layers acts as broadband coupled plasmonic resonators. Plasmon hybridization of dipolar modes is shown to be the prominent mechanism in broadband absorption.
