A new analytical method based on the surface plasmon resonance (SPR) technique is presented, with which SPR curves for both wavelength and angular modulations can be obtained simultaneously via only a single scan of the incident angle. Using this method, the SPR responses of TiO2-coated Cu films are characterized in the wavelength range from 600 nm to 900 nm. For the first time, we determine the effective optical constants and the thicknesses of TiO2-coated Cu films using the SPR curves of wavelength modula...

1.IntroductionNoble metals such as Au and Ag are the most widelyused metals in surface plasmon resonance(SPR)experimentsdue to their advantages:they display SPR bands in both thevisible and the near-infrared(NIR)frequencies,their surfacechemistry is well-
