The sensor element consists of nano-patterned gold film brought about from two-dimensional periodic photoresist templates created by holographic laser interference lithography. Reflectance spectroscopy revealed that the sensor exhibits significant refractive index sensitivity. A linear relationship between shifts in plasmonic resonances and changes in the refractive index were demonstrated. The sensor has a bulk sensitivity (SB) of 880 nm\/refractive index unit and work under normal incidence conditions. This sensitivity exceeded that of many common types of plasmonic sensors with more intricate structures. A modeled spectral response was used to study the effect of its geometrical dimensions on plasmonic behavior. A qualitative agreement between the experimental spectra and modeled ones was obtained.<\/jats:p>","DOI":"10.3390\/s19040897","type":"journal-article","created":{"date-parts":[[2019,2,22]],"date-time":"2019-02-22T03:49:44Z","timestamp":1550807384000},"page":"897","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Refractometric Sensing with Periodic Nano-Indented Arrays: Effect of Structural Dimensions"],"prefix":"10.3390","volume":"19","author":[{"given":"Daniel J.","family":"Carney","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, University of Texas at Arlington, Arlington, TX 76019, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1729-4098","authenticated-orcid":false,"given":"Halldor G.","family":"Svavarsson","sequence":"additional","affiliation":[{"name":"School of Science and Engineering, Reykjavik University, 101 Reykjavik, Iceland"}]},{"given":"Hafez","family":"Hemmati","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, University of Texas at Arlington, Arlington, TX 76019, USA"}]},{"given":"Alexander","family":"Fannin","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, University of Texas at Arlington, Arlington, TX 76019, USA"}]},{"given":"Jae W.","family":"Yoon","sequence":"additional","affiliation":[{"name":"Electronics and Telecommunications Research Institute, Daejeon 34129, Korea"}]},{"given":"Robert","family":"Magnusson","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, University of Texas at Arlington, Arlington, TX 76019, USA"}]}],"member":"1968","published-online":{"date-parts":[[2019,2,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e120","DOI":"10.4172\/2155-6210.1000e120","article-title":"The complete biosensor","volume":"4","author":"Magnusson","year":"2013","journal-title":"J.
