主　　题：Waveguide surface plasmon polaritons polymer refractive index sensor 

摘      要：A waveguide coupled surface plasmon sensor for detection of liquid with high refractive index(RI)is designed based on polymer *** effects of variation of the thickness of the Au film,polymethyl methacrylate(PMMA)buffer,and waveguide layer on the sensing performance of the waveguide are comprehensively investigated by using the finite difference *** simulations show that a thinner gold film gives rise to a more sensitive structure,while the variation of the thickness of the PMMA buffer and waveguide layer has a little effect on the *** liquid with high RI,the sensitivity of the sensor increases *** RI of liquid to be measured increases from 1.45 to 1.52,the sensitivity is as high as 4518.14 nm/RIU,and a high figure of merit of 114.07 is *** waveguide coupled surface plasmon RI sensor shows potential applications in the fields of environment,industry,and agriculture sensing with the merits of compact size,low cost,and high integration density.
