Abstract

Chirality is universally observable phenomena in the numerous physical, chemical and biological systems. It often plays a significant role there. Recently, great attentions are drawn to the artificial, chiral plasmonic metal nanostructures. In general, the naturally-occurring chiral systems exhibit quite small chiroptical properties. In contrast, the appropriately designed chiral plasmonic systems exhibit them in the highly enhanced forms because of the surface plasmon (SP) resonances. They are also promising as building blocks of the metamaterials which provide the exotic photophysical effects, such as superchiral lights and chiral optical forces [1].
