论文摘要
在本文中，提出了一个基于2.5-d欺骗表面等离子体极化（SSPP）结构和折叠的Spilt-Ring共振器（SRRS）的紧凑型拒绝过滤器。通过将折叠的SRR嵌入2.5-D SSPP传输线的周期性凹槽中，在超宽的通带中会产生一个拒绝带，从而产生了反向反应 - 频率特征。可以通过更改2.5-D SSPP拒绝单元的几何参数来独立调整过滤器的拒绝带和截止频率。由于紧凑的折叠结构，与常规的2-D SSPP排斥过滤器相比，横向尺寸降低了54％。
In this paper, a compact rejection filter is proposed based on 2.5-D spoof surface plasmon polariton (SSPP) structure and folded spilt-ring resonators (SRRs). By embedding the folded SRRs into periodic grooves of the 2.5-D SSPP transmission line, a rejection band is created in the ultra-wide passband, resulting in pass-rejection-pass frequency characteristics. The rejection band and the cut-off frequency of the filter can be adjusted independently by changing the geometrical parameters of the 2.5-D SSPP rejection unit. Because of the compact folding structure, the lateral size is reduced by 54% compared with the conventional 2-D SSPP rejection filter.
