中文摘要：

在这份报纸，我们在场基于由期刊组成的 metamaterial，两倍对称的裂口包围的兆兆赫(THz ) 的设计，模拟，制造和描述过滤器共鸣器(DS-SRR ) 数组。当电场沿着 y 方向时，我们能观察到基于 metamaterial 的过滤器拥有通带传播，并且当电场沿着 x 方向时，它拥有低通行证的传播。我们的结果证明建议过滤器能认识到由仅仅改变事件电磁波的极化方向在通带效果和低通行证的效果之间切换。而且，计算表面水流分布也被用来分析 THz metamatrial 过滤器的可切换的机制。因此，建议 THz 波浪过滤器在 THz 波浪通讯系统有潜在的应用。

英文摘要：

In this paper, we present the design, simulation, fabrication and characterization of a terahertz（THz） filter based on metamaterial consisting of the periodical double symmetric splits ring resonator（DS-SRR） array. We can observe that the metamaterial-based filter possesses a band-pass transmission when the electrical field is along y direction, and it possesses a low-pass transmission when the electrical field is along x direction. Our results demonstrate that the proposed filter can realize the switching between band-pass effect and low-pass effect by only changing the polarization direction of the incident electromagnetic wave. Moreover, the calculated surface current distributions are also used to analyze the switchable mechanism of the THz metamatrial filter. Therefore, the proposed THz wave filter has a potential application in THz wave communication systems.
