Abstract

We designed a vertical split ring resonator metamaterial to achieve a highly directive perfect absorber and emitter in the mid-infrared region based on the Generalized Kerker Condition. The results show zero backscattering and high directivity via the electric dipole-electric quadrupole interference. The metal stress-driven self-folding method was applied to fabricate the vertical metamaterial efficiently. We both experimentally and analytically demonstrated the absorption and the angular dispersion. The angle-resolved emission radiation pattern is visualized which agrees with the simulation results. This metamaterial can not only be an Infrared receiver but also an emitter. We provide a novel strategy to conceive a polarization-sensitive/-insensitive, single-/multiband, and highly directive vertical metamaterial perfect absorber and emitter in the Mid-Infrared region.
