It is utilized for sensing a galactose film. We characterized the device using the induced red shift of a Fano resonance observed in the THz transmission. The sensor has a high sensitivity of 91.7 GHz\/RIU due to a significant interaction between the galactose overlayer and the metasurface.<\/jats:p>","DOI":"10.3390\/s20082265","type":"journal-article","created":{"date-parts":[[2020,4,16]],"date-time":"2020-04-16T13:01:39Z","timestamp":1587042099000},"page":"2265","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Free-Standing Complementary Asymmetric Metasurface for Terahertz Sensing Applications"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6175-4338","authenticated-orcid":false,"given":"Fatima","family":"Taleb","sequence":"first","affiliation":[{"name":"Faculty of Physics, Philipps-Universit\u00e4t Marburg, Renthof 5, 35032 Marburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7499-0655","authenticated-orcid":false,"given":"Ibraheem","family":"Al-Naib","sequence":"additional","affiliation":[{"name":"Biomedical Engineering Department, College of Engineering, Imam Abdulrahman Bin Faisal University, Dammam 31441, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Koch","sequence":"additional","affiliation":[{"name":"Faculty of Physics, Philipps-Universit\u00e4t Marburg, Renthof 5, 35032 Marburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2075","DOI":"10.1109\/22.798002","article-title":"Magnetism from Conductors and Enhanced Nonlinear Phenomena","volume":"47","author":"Pendry","year":"1999","journal-title":"IEEE Trans.
