Abstract
- The effective parameters of artificial medium are designed to realize the perfect absorption of terahertz wave (THz), which has become one of the significant issues related to metamaterial. However, the planar structure of metamaterial has many limitations. Here, we establish a three-dimensional structure of split ring resonators (SRRs) to realize the vertically coupling SRRs and study its absorption characteristics. The results show that the absorption characteristics of three-dimensional split ring resonators have achieved 99.9% at 1.79 THz. Furthermore, by changing direction of the splits of two rings, we can get broadband absorption of more than 99% in the frequency range of 0.6 THz, which provides a design scheme for three-dimensional metamaterials and potential devices.
