Dual-Band and Multi-State Polarization Conversion Using aTerahertz Symmetry-Breaking Metadevice

Autor: Yuwang Deng, Qingli Zhou, Xuteng Zhang, Pujing Zhang, Wanlin Liang, Tingyin Ning, Yulei Shi, Cunlin Zhang

Publikováno v: Nanomaterials, Vol 13, Iss 21, p 2844 (2023)

We numerically and experimentally demonstrate a terahertz metadevice consisting of split-ring resonators (SRRs) present within square metallic rings. This device can function as a dual-band polarization converter by breaking the symmetry of SRRs. Und

Analysis of Evolution of Coupled Lorentz Resonances and Their Sensing Properties in Terahertz Metamaterials

Autor: Nan Jiang, Ziye Zhang, Wanlin Liang, Yuwang Deng, Pujing Zhang, Cunlin Zhang, Qingli Zhou

Publikováno v: Frontiers in Physics, Vol 10 (2022)

Combined with experimental and simulated results, the resonances and metamaterial-induced transparency have been theoretically investigated using the Lorentz oscillator model for terahertz metamaterials with unequal-length bar structures. The bar spa
