我们提出了一种在微波和太赫兹频率下产生频率选择性欺骗表面等离子体激元（SPPs）的金属结构。设计在薄介质基板上，金属波纹结构由两个相对取向的单面波纹带组成，这两个单面波纹带耦合到两个双面波纹带。该结构由传统的共面波导（CPW）馈电。为了实现CPW模式和SPP模式之间的平滑转换，还设计了两个过渡段。我们制作并测试了微波频段的频率选择性欺骗SPP结构。测量结果表明，在7 ~ 10 GHz的选择频段内，反射系数小于-10 dB，传输损耗约为1.5 dB，与数值模拟结果吻合较好。 该结构可用作SPP滤波器，在选择频带内具有低损耗、高传输率和宽带宽的良好性能。
We propose an ultrathin metallic structure to produce frequency-selective spoof surface plasmon polaritons (SPPs) in the microwave and terahertz frequencies. Designed on a thin dielectric substrate, the ultrathin metallic structure is composed of two oppositely oriented single-side corrugated strips, which are coupled to two double-side corrugated strips. The structure is fed by a traditional coplanar waveguide (CPW). To make a smooth conversion between the spatial modes in CPW and SPP modes, two transition sections are also designed. We fabricate and measure the frequency-selective spoof SPP structure in microwave frequencies. The measurement results show that the reflection coefficient is less than -10 dB with the transmission loss around 1.5 dB in the selective frequency band from 7 to 10 GHz, which are in good agreements with numerical simulations. The proposed structure can be used as an SPP filter with good performance of low loss, high transmission and wide bandwidth in the selective frequency band.
