We report in this talk strong broadband absorption resonances mid- and near-infrared frequencies from our nanometer size metamaterial resonators. We report a systematic study of these resonances with different dimensions of the resonators and their spacing, combined with our theoretical simulations. We will present our experimentally measured reflection at different incidence angles, and transmission of those resonators with different feature sizes and different lattice spacings which control the coupling between neighboring units. We found distinctively strong and broadband resonance in the spectrum of the resonators. We will discuss how our results can be used to introduce strong electric and magnetic responses and could provide a route to broadband negative refraction.
