Abstract:In this paper, a composite structure metamaterial absorber is designed and simulated with dual metallic particles and holes array. The absorption peak of the proposed metamaterial absorber is excited by the resonance of localized surface plasmon (LSP) modes. The vertical distance (along the x-axis) and horizontal distance (along the y-axis) between two metallic particles are optimized. The absorption of the proposed metamaterial absorber is enhanced due to new LSP modes are excited. Moreover, new absorption bands are obtained with optimizing vertical distance and horizontal distance.
