Dispersion properties of compact single- and double-side grooves SSPPs are analyzed and compared. The combination of two single-side grooves with opposite phases can sustain the odd-mode SSPPs, which is contrary to the dominantly even mode SSPPs existed on metal-dielectric interfaces in optical frequencies or on structured metal surfaces in the lower frequencies. Two low-pass filters based on odd-mode SSPPs working at 0–7 and 0–14.1 GHz are fabricated and measured. Both simulations and measurements validate that the proposed SSPPs structure can realize high-efficiency excitation of odd-mode SSPPs and low-loss transmission properties.

奇模欺骗表面等离子体激元极化子的激发及其在低通滤波器中的应用

分析并比较了紧凑的单面和双面凹槽SSPP的分散特性。具有相反相位的两个单侧凹槽的组合可以维持奇模SSPP，这与光频率在金属-电介质界面上或低频的结构化金属表面上存在的显性偶模SSPP相反。制作并测量了两个基于零模SSPP的低通滤波器，它们在0–7和0–14.1 GHz下工作。仿真和测量结果均表明，所提出的SSPP结构可以实现奇模SSPP的高效激励和低损耗传输特性。
