Abstract:

We report a perfect metasurface structure-based optical absorber consisting of a tri-layer metaldielectric-metal system in ultraviolet band. Optical power absorption of over 91% has been observed in entire ultraviolet band, and can even reach to the level of as high as 99% in a certain local near waveband. Unique properties of the perfect absorption are independent on polarization state of the incoming light, and insensitive to variation of structural dimension. We discuss the effect of geometrical parameters of the structure such as height and radius on the basis of theoretical calculation results. In addition, the influence of materials upon performance of the absorber is presented. The efficient light absorption can be attributed to plasmonic resonance.
