Figure 2.
Orientation averaged OD as a function of wavelength under the OAM incident beam when the nanocomposites locate at 
(olive line), 
(red line) and 
(blue dark line), respectively. The corresponding signals for the mirror reflected system are presented as green (
), pink (
), blue (
). (a,b) correspond to the system of a metal nanoparticle and chiral molecule with 
and 
, respectively. (c,d) to the system of a NP dimer and a chiral molecule with 
and 
, respectively. (e,f) describe 
as a function of position for the incident OAM beam with 
and 
at the wavelength of 300 nm, respectively.
