Study on 2D Plasma Photonic Crystals with Defect Modes Using FDTD Method

In this paper, a typical uniform unmagnetized two-dimensional plasma photonic crystal with a single linear defect mode is simulated based on the finite difference time domain method, and the effects of defect mode position and size on its photonic band gaps characteristics are explored respectively. the research can provide an idea for tuning the electromagnetic properties of two-dimensional plasma photonic crystals.
