Selective Enhancement of Optical Chirality and Spin Angular Momentum in Plasmonic Near-Field
Naoki Ichiji, Takuya Ishida, Ikki Morichika +3
The interaction between circularly polarized (CP) light and matter is governed by two fundamental quantities: spin angular momentum (SAM) and optical chirality (OC). While these qu…
