Building blocks including rectangles, cut wires, crosses, fishnets, split ring resonators were ordered on suitable substrates and their reflection (R), transmission (T), and loss energy (L) spectra were calculated. The numerical studies were performed using our efficient in-house two-dimensional rigorous coupled-wave analysis technique. Our technique incorporates all the key improvements of the method available, taking into account both proper Fourier factorization rules, adaptive spatial resolution techniques, as well as structural symmetries. Using the R, T, and L spectra, we investigated spectral sensitivity of SPR and calculated the respective SPR sensor characteristics, such as figures of merit (FOM), enabling direct comparison of various structural morphologies for potential sensing applications. Also, optimization of the structures in terms of FOM has been performed to identify the most promising candidates. Additionally, to allow for interpretation of spectral resonant features and the interplay of individual and surface lattice resonances, we were gradually changing the morphology of individual building blocks from one type of element to another one. We believe that this study will bring insight into plasmonic behavior of nanostructured metasurfaces and will further benefit research into SPR biosensors Pracoviště Ústav fotoniky a elektroniky Kontakt Petr Vacek, vacek@ufe.cz, Tel.: 266 773 413, 266 773 438, 266 773 488 Rok sběru 2016
