Dynamically tunable Fano resonance with high Q factor based on asymmetric Dirac semimetal split-ring structure
We propose an asymmetric split-ring (ASR) structure based on Dirac semimetal, which has Fano resonance with a high quality (Q) factor in the terahertz (THz) band, the Q factor can reach a maximum value of 20.19. Amplitude modulation can be achieved by increasing the degree of asymmetry Δ θ of the as...
