Sensitivity-Enhanced SPR Sensor Based on Graphene and Subwavelength Silver Gratings
A novel surface plasmon resonance (SPR) sensor with graphene and subwavelength gratings is proposed to improve the sensing performance. A series of numerical analyses were performed to investigate the effect of structural parameters on the sensing performance, such as minimum reflectance at resonanc...
