plasmon,Mie resonance

Both plasmon resonance excited in noble metal nanoparticles and Mie resonance excited in semiconductor nanoparticles confine the optical electromagnetic field, while intensity and spatial characteristics of confined field depend on the excited mode. Assembly formed by noble metal and semiconductor nanoparticles exhibit resonance enhancement of the optical chiral field. In this study, we will clarify the correlation between the resonant mode and the optical chiral field.
