Comparison with linearly arranged particles by different polarized light. a Reflectance spectra of different silver particle-film system. The blue and pink solid lines represent the reflectance spectra of the linear silver particle chain-film system excited by left-hand circle light (marked as LCP(L)) and linear polarized light (marked as LP(L)), respectively. The structure of linear particle chain-film is shown in the inset. In the diagram, Arabic numerals 20, 30, 40, and 50 represent the radius of corresponding particles. b The electric field enhancement spectra in the gaps between particle-film in the chiral particle chain-film and the linear particle chain-film systems. The gaps between particle-film are respectively labeled as F1, F2, F3, and F4, which are indicated in the insets. The blue and pink solid lines represent the enhancement on the film in the linear chain structure excited by left-hand circle light (marked as LCP(L)) and linear polarized light (marked as LP(L)), respectively. The blue and red dotted lines are electric field enhancement for the chiral particle chain-film system probed by LCP and RCP light, respectively. The vertical dashed lines from left to right correspond to the peaks at 590, 635, 710, and 785 nm, respectively
