| description | In this article, a highly sensitive surface plasmon resonance (SPR) based biosensor is proposed, Kretschmar’s configuration with angular interrogation as the most successful and popular technique has been used, a laser with 664 nm is impinged on a device that consists of a stratified medium that includes perovskite ( ), a transfer matrix method for a p-polarized coherent and collimated incident laser beam is used to calculate the reflectivity, and this proposed device is more sensitive for a medium with refractive indices between 1.34 to 1.40. In order to obtain a high enough sensitivity, four different configurations have been brought to the reader’s attention. The device has been introduced with the aid of some important quantities to measure the sensitivity, figure of merit (FoM), full width at half-maximum (FWHM) and detection accuracy (DA), their results respectively are , . Finally, these performances are far better than the first simple configuration, and the simulation results are implemented in Matlab codes. |
