This work demonstrates, for the first time, a spatially dependent metamaterial perfect absorber operating in the infrared regime, and achieves an experimental absorption of 97% at a wavelength of 6.0 μm.Abstract:
We demonstrate, for the first time, a spatially dependent metamaterial perfect absorber operating in the infrared regime We achieve an experimental absorption of 97% at a wavelength of 60 microns, and our results agree well with numerical full-wave simulations By using two different metamaterial sublattices we experimentally demonstrate a spatial and frequency varying absorption which may have many relevant applications including hyperspectral sub-sampling imagingread more
