METHOD OF CHANGING A CIRCULAR DICHROISM SPECTRUM OF AN ELECTROMAGNETIC WAVE

摘要

Various embodiments may provide a method of changing a circular dichroism (CD) spectrum of an electromagnetic wave. The method may include providing a chiral structure. The method may further include providing said electromagnetic wave to the chiral structure. The method may also include rotating the chiral structure to change the circular dichroism spectrum of said electromagnetic wave. The chiral structure may be a planar structure, and may be a nanostructure array comprising a plurality of nanostructure arrangements, wherein each nanostructure arrangement comprises one or more gammodion, spiral, triangular nanostructures, or nanorods and nanodisks in a windmill arrangement.
