中文摘要:在本文中,我们设计和仿真了一种包含双金属颗粒和孔阵列的符合结构超材料吸收器。该超材料吸收器的吸收峰是由于局域表面等离激元激发的。在仿真过程中双金属颗粒之间的垂直距离和水平距离被优化。由于新的LSP模式的激发导致该吸收器的吸收性质得到增强。同时,在哟花垂直距离和水平距离的过程中新的吸收带形成。

Enhance absorption based on the resonance of localized surface plasmon modes in a metamaterial absorber
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.
