摘　　要：采用传输矩阵方法和菲涅尔公式,根据THz频段不同区域内材料折射率的特点,计算模拟了聚合体聚偏氟乙(polyvinylidene fluoride,PVDF)/聚碳酸酯(polycarbonate,PC)一维光子晶体对THz波的反射作用.结果表明这种反射在亚太赫兹频段具有较好的反射性能和较大的反射带宽.此外,根据计算结果,本文还对THz反射器的理论研究设计进行了讨论.Terahertz （THz） wireless communication system, which exhibits great potential in the future short-range wireless communications, is known to be a kind of ultra-broadband system with high data rates. THz sources, modulators and detectors are key elements in these systems, while in order to maintain high-quality connection, the THz reflectors are also very important. Here, a reflector which is a kind of one-dimensional photonic crystal made of polyvinylidene fluoride （PVDF）/polycarbonate （PC） is studied carefully. According to the refractive indices of materials in the THz range, the reflection coefficients for THz waves are obtained through transfer-matrix method and Fresnel formula calculation. We demonstrate that, in sub-THz waveband, this device shows high performance and wide reflection band. Furthermore, based on the calculation, the research and the design of THz reflectors are also discussed in this article.
