摘要
本文设计了一种基于双"十"形结构的手性超材料,用数值仿真技术研究分析了其非对称传输特性。结果表明在谐振频率为7.33GHz和9.58GHz时,非对称传输系数分别可达0.75和0.84,由此可知此结构在微波段具有较好的非对称传输特性。该超材料具有结构简单、成本低、易制备等优点,对实现电磁开关等超材料功能器件具有重大意义。
A kind of chiral mictamiatcrial was designed and constructed in the form of double cross-shaped structure. Itsasymimictric transmiission characteristics were analyzed by simulation. The results showed tsion coefficient could reach 0.75 and 0.84 at around 7.33 GHz and 9.58 GHz respectively, with good asymimictric transmiission characteristics in the miicrowave frequencies. Furthcrmiore, this mictamiatcrial has miany advantages, suchas simplestructure,low cost and easy fabrication. It could provide an important opportunity for developing various mictamiatcrial-based functional devices.
