Metamaterial absorbers open a new door for the design of optical harvesting devices ranging from the microwave to optical regimes. The top resonator in these structures is critical for the function of metamaterial absorbers. The resonant frequency, bandwidth, and maximum absorption mainly depend on the choice of material, shape, and size of the top resonator. The maximum absorption is generally impaired as the size of the resonator changes, due to the high sensitivity of impedance matching with the medium. In this paper, we experimentally demonstrate a metamaterial perfect absorber with unabat
