Autor: Bowen Tan, Xingcheng Xiang, Longcheng Feng, Shengxin Yang, Wei Zhang, Caihong Zhang, Jingbo Wu, Kebin Fan, Biaobing Jin, Jian Chen, Huabing Wang, Peiheng Wu
Publikováno v: Applied Physics Letters. 122:151101
Subwavelength-sized metallic structures exhibit extraordinary responses to electromagnetic waves due to their geometry, generating surface plasmon polaritons (SPPs) at the metal–dielectric interface. The development and application of terahertz (TH

Real-time near-field terahertz spectroscopy imaging
Autor: Chen Du, Jian Chen, Peiheng Wu, Biaobing Jin, Shengxin Yang, Jingbo Wu, Caihong Zhang, Longcheng Feng
Publikováno v: 2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz).
In this work, we applied terahertz near-field microscope based electro-optic sampling to animal tissue imaging. As a label-free diagnostic technique, fast THz near-field imaging system with a micrometer-scale spatial resolution can be constructed as

Anisotropic coding metasurfaces and their active manipulation based on vanadium dioxide for multifunctional applications in the terahertz region
Autor: Shilei Liu, Chunmei Ouyang, Zhibo Yao, Jing Zhao, Yanfeng Li, Longcheng Feng, Caihong Zhang, Biaobing Jin, Jiajun Ma, Hongyi Li, Yi Liu, Quan Xu, Jiaguang Han, Weili Zhang
Publikováno v: Optics Express. 30:28158
Various kinds of metasurfaces have been proposed because they can be tailored to achieve the desired modulations on electromagnetic wave that do not occur in nature. Compared to conventional metamaterials, coding metasurfaces integrated with informat

Autor: Jing Zhao, Quan Xu, Yanfeng Li, Biaobing Jin, Jiaguang Han, Shoujun Zhang, Weili Zhang, Xieyu Chen, Caihong Zhang, Yi Liu, Jiajun Ma, Longcheng Feng, Chunmei Ouyang
Publikováno v: Optics Express. 29:21738
Active control of metasurfaces has attracted widespread attention because of the adjustable electromagnetic properties obtained. Here we designed and experimentally studied a dynamically controllable polarization converter in the terahertz band. By d
