چکیده انگلیسی
Magneto-plasmonic response in planar multilayer with prism coupling composed from Fe/Au bi-layer supplied by photonic crystal (Ta2O5 / SiO2 bi-layers) is studied. Modeled structure is intended as a sensor unit combining magneto-optical (MO) and surface-plasmon-resonance (SPR) effects. The sensitivity of MO-SPR system by small variations of analyte refractive index is tested to obtain optimal resolution ability. The non-reciprocal MO-SPR response is studied by means of the function Ï(Ï)â¯=â¯(Rp(+)â¯ââ¯Rp(â))/(Rp(+)â¯+â¯Rp(â)), where the reflectance Rp depends on the incidence angle Ï and external magnetic field orientation by a fixed wavelength. The detection ability is characterized by the angular shift ÎÏ0 between the null-points of the function Ï that corresponds to the change Îna of analyte refractive index. Besides the key role of metallic layers thicknesses the number and size of Ta2O5/SiO2 bi-layers of photonic crystal are discussed. The magneto-plasmonic response in planar multilayer with prism coupling composed from Fe and Au bilayer supplied by photonic crystal (Ta2O5 / SiO2) is studied. Modeled structure is intended as a sensor unit combining MO and SPR effects.
