Numerical analysis of a Kretschmann surface plasmon resonance sensor with silver/TiO₂/BaTiO₃/silver/graphene for refractive index sensing

Abstract

The sensitivity of a Kretschmann surface plasmon resonance (SPR) sensor was analyzed. The Kretschmann setup had multiple layers, a BK7 prism, silver, barium titanate (BaTiO₃), titanium dioxide (TiO₂), and graphene. The BaTiO₃ and TiO₂ coatings were sandwiched between two silver layers. The sensitivity of 260°/RIU has been achieved. The graphene layers are added to the configuration to improve sensitivity and as a bio-compatibility agent. This configuration can be used for biochemical sensors.
