摘要

基于矩形结构,我们在光学区创建了双波段超材料完美吸收体(DMPA)。独立极化吸收是一个显著的优势,也是组成材料的简单集成进展。特别是,在140太赫兹(608太赫兹至748太赫兹)的带宽范围内,吸收率超过90%,并且在te偏振的斜入射角范围内仍然保持良好。我们的结果可以被认为是不久的将来应用的基础,如光电探测器,能量转换器等。

A Rectangle-quartet Metamaterial for Dual-band Perfect Absorption in the Visible Region
Based on rectangle-shaped structures, we create a dual-band metamaterial perfect absorber (DMPA) in the optical region. The independent-polarization absorption is a significant advantage as well as the simple integrated progress for constituent materials. In particular, absorption can be obtained to be over 90% in a bandwidth of 140 THz (from 608 THz to 748 THz), which is still remained well in the oblique incident angles for the TE-polarization. Our results can be regarded as the groundwork for the near future applications such as photodetectors, energy converters and more.
