【摘要】 为了更简便的制备宽带内的左手材料,提出一种新型的X波段方形开口磁谐振器(SSRs),通过将该磁谐振器与H型电谐振器的耦合,设计了一种电路板单面印刷的宽带左手材料(Left Hand Materials,LHMs).经过HFSS(High Frequency Structure Simulator)仿真,利用散射参量法计算分析了SSRs、H型谐振器的传输特性和负电磁参数特性、电磁谐振器耦合结构的负介电常数、负磁导率和负折射率.仿真证实:该结构在10.05～11.6GHz频带内具有负折射特性,较同频段其他LHMs带宽更宽.同时耦合结构可以单面印刷,尺寸较大,在一定程度上避免了传统LHMs对印刷电路板刻蚀工艺加工精度的较高要求,便于实际制备.更多还原

【Abstract】 In purpose of making preparation of wideband left handed materials(LHMs) more simple,a newly designed split square resonator(SSRs) of magnetics at X-band is presented.A single layer printed wideband left hand material is realized by this kind of magnetic resonator coupled with H-shaped electric resonators.With the simulation of HFSS,the properties of transmission,reflection and the negative electromagnetic parameters of both SSRs and H-shaped resonators are calculated and analyzed by the S-parameter retrieval method.The double negative of permittivity and permeability,and the negative refractive index are also carefully retrieved and studied.It is proved that the proposed LHMs has negative refraction in 10.05~11.6 GHz band,which is wider than other LHMs in the same frequency band.The proposed LHMs can reduce the difficulties in fabrication through PCB to a certain extent.It may be expected to accelerate the practical applications.更多还原
