[期刊论文] 作者：NIUChao,CHANGSheng-jiang,
来源：OptoelectronicsLetters 年份：2012
This paper proposes an optical device which can continuously change the polarization state of terahertz (THz) waves. The device consists of metal gate, anti-reflection coatings, liquid crystal and mirror. By changing the refractive index of......
A novel terahertz device with multi-function of polarization and switch based on phase transition of
[期刊论文] 作者：GUWen-hao,CHANGSheng-jiang,FANFei,
来源：OptoelectronicsLetters 年份：2016
A terahertz (THz) polarizer and switch structure is proposed based on the phase transition of vanadium dioxide (VO2). When VO2is in the insulation phase, the resonance frequencies of the proposed structure are 1.49 THz and 1.22 THz f...
[期刊论文] 作者：ZHENGWei,LIWei,CHANGSheng-jiang,
来源：OptoelectronicsLetters 年份：2015
A thermally tunable terahertz metamaterial absorber (MA) with InSb embedded in a metal-dielectric-metal structure is proposed. The transmission and tuning properties of the proposed metamaterial absorber are analyzed for the temperature ran......

A metamaterial based on complementary planar double-split-ring resonator (DSRR) structure is presented and demonstrated, which can optically tune the transmission of the terahertz (THz) wave. Unlike the traditional DSRR metamaterials, the D......
A thermally tunable terahertz bandpass filter with insulator- metal phase transition of VO2thin film
[期刊论文] 作者：LIWei,CHANGSheng-jiang,WANGXiang-hui,LINLie,BAIJin-jun,
来源：OptoelectronicsLetters 年份：2014
A terahertz bandpass filter with the sandwich structure consisting of thermally tunable vanadium dioxide (VO2) thin film, silica substrate and subwavelength rectangular Cu hole arrays is designed and theoretically analyzed. The results show......
