The data of the article "Chiral Optomechanical Effects and Near-Field Optical Properties of Chiral Core-Dielectric-Ag Concentric Sphere Structures”

The dielectric function of silver in the calculation is taken from experimental measurements by Johnson and Christy. The chiral medium is described using a constitutive relationship, and the optical torque and force are obtained using the Maxwell stress tensor method.

The submitted dataset includes the scattering cross sections and optical torques of pure chiral spheres, chiral nucleus medium shells, chiral nucleus Ag shells, and chiral nucleus medium layer Ag shells as a function of wavelength, corresponding to Figure 2 in the text; The wavelength dependent CD signal data of chiral particles placed in the near-field of the four structures mentioned above correspond to Figure 4 in the text; The scattering cross-section and optical torque data of structures with different Ag shell thicknesses as a function of wavelength correspond to Figure 5 in the text; The scattering cross section and optical torque data of structures with different chiral nuclei and relative dielectric constants as a function of wavelength correspond to Figure 6 in the text; The scattering cross-section, optical torque, and electric field and chiral density distribution data at corresponding resonance wavelengths of structures with different dielectric layer thicknesses correspond to Figure 7 in the text; The scattering cross section and optical torque data of structures with different refractive indices of the dielectric layer as a function of wavelength correspond to Figure 8 in the text.
