Research of Subwavelength Metal Hole Arrays Used for Surface Plasmon Resonance Sense
In this paper, a new structure with square metal hole arrays was devised for SPR sense, and it was optimized by numerical calculation based on finite element analysis. After optimization, a very narrow SPR peak, which is just tenth of the conventional SPR sensor, can be obtained in the transmission spectrum. Besides, the linear measuring range is more than 0.4 RIU. Consequently, the newly designed structure will be benefit for the ability of resist noise and resolution.
