可用于60GHz通信的C型结构超材料的设计
|
摘要
在S型结构超材料的启发下,对C型结构电磁理论分析,通过设计单元尺寸在60GHz附近的通带内同时实现电谐振与磁谐振.通过运用Matlab软件对HFSS仿真结果进行参数提取,可以得知该通带内介电常数(ε)和磁导率(μ)均为负值.与S型结构相比,该结构较为简单便于实物制作,并且还可以根据实际需要,改变尺寸参数较容易地实现左手频段的移动.60GHz无线通信具有传输速率高、抗干扰性强等优点,因而成为当前的一个研究热点,将C型结构左手材料运用到该通信中,具有一定的科技意义.
Inspired by S meta-material structure, this paper analyzes the electromagnetic theory C-type structure, and achieves electrical resonance and magnetic resonance at the band-pass near 60 GHz by designing the cell size. Using mat-lab software to extract HFSS simulation result parameter, it can learn that the pass-band permittivity(ε) and magnetic permeability(μ) are negative in the pass-band.Compared with S type structure, the structure is relatively simple to facilitate physical production, and the left band can be move easily by change of size parameters according to actual need. 60 GHz wireless communication has many advantages, such as high transmission speed, strong anti-interference ability, and so on, so it has become a hot research topic at present. When applied to communication,the C-type structure LHM has a certain scientific and technological significance.
