P14 – Dynamically tunable Graded Index Photonic Crystal lens based on Dirac semimetal

Panahianfar P., Rezaei B.

In this paper, we design a graded-index photonic crystal based on Dirac semimetals and simulate the light propagation in the proposed structure using two-dimensional finite-difference time-domain method. The numerical results indicate that the designed GRIN PC has focusing capability for incident light at terahertz frequency range, and its focal distance can be tuned through changing […]
