    AG-NI BIMETALLIC FILM ON CAF2 PRISM FOR HIGH SENSITIVE SURFACE PLASMON RESONANCE SENSOR
    (Photonics Letters of Poland, 2021-09-30) Ananthan, Nisha; Pandaram, Maheswari; Santhanakumar, Subanya; Ponnusamy, Munusamy Anbarasan; Karuppaiya, Balasundaram Rajesh; Zbigniew, Jaroszewicz
    We present a surface plasmon resonance (SPR) structure based on Kretschmann configuration incorporating bimetallic layers of noble (Ag) and magnetic materials (Ni) over CaF2 prism. Extensive numerical analysis based on transfer matrix theory has been performed to characterize the sensor response considering sensitivity, full width at half maxima, and minimum reflection. Notably, the proposed structure, upon suitably optimizing the thickness of bimetallic layer provides consistent enhancement of sensitivity over other competitive SPR structures. Hence we believe that this proposed SPR sensor could find the new platform for the medical diagnosis, chemical examination and biological detection.
