| 摘要: |
| 应用传输矩阵推导出了光脉冲通过一维光子晶体时电、磁场时空的分布函数;同时以Gaussian脉冲为例,指出任意空间位置,电场和磁场随时间变化大体上均保持为高斯分布;从入射端到出射端电,磁场的幅度逐渐衰减,而且电场的节点处正对应着磁场的峰值处。 |

| Abstract: |
| Applying transmission matrix,the author gets distribution function of eletric field and magnetic field when pulse crosses 1DPCs.At the same time,the author uses Gaussian pulse to point out that the change of electric field and magnetic field keeps Gaussia |
