Simulation of circular dichroism enhancement in gold nanocuboids array lled by chiral medium for optical frequency range

The work is devoted to the numerical simulation of circular dichroism amplification system based on a gold nano cuboids periodic array. We found the optimal configuration for amplifying circular dichroism by more than 30 times. We also demonstrated possible variants of optimization for achievement of controllable red shift of amplification band and amplification factor within variations of structure height, period and angle of incidence.
