摘      要：A high-sensitivity metal-coated long-period fiber grating(LPFG) sensor based on material dispersion is *** on the coupled mode theory,the influence of the material dispersion on the dual-peak characteristics of the metal-coated LPFG is *** considering the material dispersion,the jumping region of the dual-resonant-wavelength shifts toward the thinner film thickness,and the sensitivity of the dual-peak metal-coated LPFG sensor to liquid refractive index(RI) can be obtained to supply accurate parameter ***,two kinds of silver-coated LPFGs with different film thicknesses and grating periods are fabricated to monitor the salt solution,and the sensitivities of these two sensors are *** experimental results are consistent with the theoretical analyses.
