Özet
In this paper, we present a design, simulation, and measurement of a single broad-band metamaterial absorber composed of a consecutive layer of conical-shaped SiO2/Al/SiO2/Al. The circular symmetry of the conical-shaped resonator makes the metamaterial absorber polarization insensitive so that the full intensity of the sunlight can be harvested. The physical behavior of the broad-band mechanism is investigated both numerically by finite difference time domain (FDTD) and experimentally. The numerical calculations indicate the origin of broadband absorption is due to the couplings between the two metal layers sandwiched in between two dielectric SiO2 layers. The effect of geometrical parameters and the layer thicknesses are studied numerically and experimen-tally. The experimental results show the average absorption strength of the metamaterial absorber is around 80% within the spectral range of 400-1000 nm. The experimental and simulation spectra are well-consistent. The proposed platform has potential use in many potential applications, such as solar cells, photodetectors, cameras, etc.
