THEORETICAL INVESTIGATION OF A DOUBLE-RESONANCE PLASMONIC IN MULTILAYER STRUCTURE INTENDED FOR BIOMEDICAL DETECTION

The photo electronic devices based on surface plasmon resonance (SPR) phenomena have wide applications in the biomedical field. The biological environments to be detected are influenced by the SPR phenomenon, perhaps by the wavelength or the angle of incidence of resonance. In this work, the angular analysis of the phenomenon of double SPR in multilayer nanostructures is modeled by the transfer matrix method (T matrix). Consequently, we find that we can eliminate the error of simple SPR response and double SPR response based on the absolute deference response between the first SPR resonance and the second SPR double resonance.
