Perfect narrowband circular dichroism based on intrinsic chiral dual quasi-bound states in the continuum in terahertz metasurfaces

Circular dichroism (CD) of chiral structures has wide applications in ultra-sensitive biosensing, wavefront manipulation, and other fields. However, 3D chiral structures require a complex fabrication process, and 2D non-intrinsic chiral structures are difficult to achieve narrow-band perfect CD. Her...
