An analysis of the propagation characteristics of the designed structure is discussed employing the finite element method (FEM). The calculation results revealed that a Fano resonance outline emerged, which results from an interaction between the continuous broadband state of the waveguide with two symmetric triangle stubs and the discrete narrowband state of the CSRRC. The influence of geometric parameters on sensing properties was studied in detail. The maximum sensitivity reached 1500 nm\/RIU with a high figure of merit of 65.2. The presented structure has great applications for on-chip plasmonic nanosensors.<\/jats:p>","DOI":"10.3390\/s19224972","type":"journal-article","created":{"date-parts":[[2019,11,15]],"date-time":"2019-11-15T11:24:32Z","timestamp":1573817072000},"page":"4972","update-policy":"https:\/\/summer-heart-0930.chufeiyun1688.workers.dev:443\/https\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Fano Resonance in a MIM Waveguide with Two Triangle Stubs Coupled with a Split-Ring Nanocavity for Sensing Application"],"prefix":"10.3390","volume":"19","author":[{"given":"Xiaoyu","family":"Yang","sequence":"first","affiliation":[{"name":"School of Instrument and Electronics, North University of China, Taiyuan 030051, China"},{"name":"School of Electrical Engineering, Zhejiang University of Water Resources and Electric Power, Hangzhou 310018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ertian","family":"Hua","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering, Zhejiang University of Water Resources and Electric Power, Hangzhou 310018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengmeng","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Instrument and Electronics, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yifei","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Instrument and Electronics, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Wen","sequence":"additional","affiliation":[{"name":"School of Instrument and Electronics, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shubin","family":"Yan","sequence":"additional","affiliation":[{"name":"School of Instrument and Electronics, North University of China, Taiyuan 030051, China"},{"name":"School of Electrical Engineering, Zhejiang University of Water Resources and Electric Power, Hangzhou 310018, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"824","DOI":"10.1038\/nature01937","article-title":"Surface plasmon subwavelength optics","volume":"424","author":"Barnes","year":"2003","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"132","DOI":"10.1016\/j.optcom.2016.07.068","article-title":"Comparison of finite element and transfer matrix methods for numerical investigation of surface plasmon waveguides","volume":"382","author":"Haddouche","year":"2017","journal-title":"Opt.
