Nanoantenna、Circular Dichroism

Twisted metamaterials, created by stacking and twisting two achiral nanostructured layers exhibit chirality. We propose a simple method employing nanoantenna stickers to fabricate such metamaterials, achieving precise control of giant circular dichroism via twist angle adjustment with the largest effect at 22.5°, holding promise for chiral optics and sensing development.
