Near a circular silver nanostructure, spin angular momentum and optical chirality of circularly polarized light can be enhanced at different wavelengths, and the two are controlled by different field-interference mechanisms.
In particular, we consideredg= 0.003iandg= 0.003 in the simulation withϵ= 1.43

Selective Enhancement of Optical Chirality and Spin Angular Momentum in Plasmonic Near-Field
Near a circular silver nanostructure, spin angular momentum and optical chirality of circularly polarized light can be enhanced at different wavelengths, and the two are controlled by different field-interference mechanisms.
