In this paper, a new structure for efficiency enhancement of metamaterial absorber in visible range of spectrum is proposed. The proposed structure is analyzed using FEM method. The results show that by changing the parameters of the proposed structure, the absorbance will increase to 100%. Also, we investigate the effect of the angle between two ellipses on the absorbance spectrum of metamaterial absorber. Simulation results show that metamaterial absorber has a significant preference in comparison to non-metamaterial absorber when illuminated with unpolarized light. The proposed metamaterial absorber consists of three gold nano-layers that are separated by two Si3N4 nano-layers.
