Circular dichroism enhancement induced by surface plasmons in the structure of a metallic grating coated by chiral TDBCs

We investigate the enhancement of the circular dichroism (CD) spectrum in a metallic grating by coating it with chiral TDBCs. Using the finite difference time domain method, we obtain reflection spectra and CD spectra. The amplification of TDBCs chirality is achieved through the excitation of both s...
