The system consists in an initially opaque holey metal film whereby the introduction of a gas provokes the appearance of spectral features in transmission and reflection, due to the phenomenom of absorption-induced transparency (AIT). The peaks in transmission and dips in reflection observed in AIT occur close to the absorption energies of the molecules, hence its name. The presence of the gas would be thus revealed as a strong drop in reflectivity measurements at one (or several) of the gas absorption resonances. As a proof of principle, we theoretically demonstrate how the AIT-based sensor would serve to detect tiny amounts of hydrocyanic acid. 000070596 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/MAT2014-53432-C5-1-R 000070596 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000070596 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000070596 700__ $$aChristos, Argyropoulos 000070596 700__ $$aMonti, Alessio 000070596 773__ $$g3 (2016), 11$$pEPJ, Appl. metamater.$$tEPJ Applied Metamaterials$$x2272-2394 000070596 8564_ $$s713431$$uhttps://zaguan.unizar.es/record/70596/files/texto_completo.pdf$$yVersión publicada 000070596 8564_ $$s119119$$uhttps://zaguan.unizar.es/record/70596/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000070596 909CO $$ooai:zaguan.unizar.es:70596$$particulos$$pdriver 000070596 951__ $$a2020-03-31-10:30:01 000070596 980__ $$aARTICLE
