Abstract
In this paper a new sensing configuration with enhanced sensitivity utilizing 2D materials on the bimetallic layers of Magnetic Material Ni over Ag for Kretschmann configuration is proposed and analyzed numerically using Fresnel equation and transfer matrix method. Results show that
such a hybrid configuration with well optimized thickness of metallic layer and utilization of specific no. of 2D materials can increases the sensitivity as high as 298°/RIU is absorbed for the configuration consist 10 nm of Ni over 40 nm thickness of Ag added with a 2 layers of WSe2.
