摘要
从Maxwell方程出发,应用辛时域有限差分方法对一维真空等离子光子晶体进行分析,分别用辛算法T2S2、T2S4模拟了电磁脉冲在一维真空等离子体光子晶体结构中的传播过程。然后,从频域的角度分析了等离子体-真空光子晶体的电磁反射系数。计算结果表明了辛时域有限差分方法与传统FDTD相比,计算精确性更高。
From the Maxwell equation, the method of symplectic finite-difference time-domain is applied in analyzing one-dimensional plasma photonic crystal.The propagation process of electromagnetic pulse in one-dimensional vacuum plasma photonic crystal structure is simulated by symplectic algorithm T2S2, T2S4 respectively. Then, from the perspective of frequency domain, the reflection coefficient of the plasma-vacuum photonic crystals is analyzed. The results show that the symplectic finite-difference time-domain method is accuracy and correctness.
