Abstract (Summary)

We propose a theoretical dispersive prism that will increase the resolution of refractive-index sensing for prism coupling in the Kretschmann-Raether (KR) configuration compared with the conventional nondispersive prism. The resonant surface plasmon polariton (SPP) mode is identified and the variables for optimal resolution using a nondispersive prism are analyzed. An iterative curve-fitting technique is applied to the refractive-index curve for a theoretical dispersive prism. Our results show that compared with the nondispersive prisms conventionally selected, our novel dispersive dielectric material increases the resolution for sensing by 77.8%.
