| 摘 要： | 利用时域有限差分法对电磁脉冲模拟器辐射天线产生的电磁场进行数值模拟,在分析卷积完全匹配层(CPML,convolutional perfectly matched layer)原理的基础上,分别选用CPML和修正的完全匹配层(MPML)两种吸收边界条件进行对比分析,仿真结果表明CPML不仅可以吸收传播模,而且还能够有效吸收低频凋落波,获得了很好的截断效果,展示了其在电磁脉冲模拟器数值模拟中的应用前景。 |

| Abstract: | The radioactive near field emitted by a small-size EMP radiator was analyzed by the finite-difference time-domain algorithm.The principle of the convolutional perfectly matched layer(CPML) was demonstrated,and both the CPML and the modified perfectly matched layer(MPML)absorbing boundary conditions were used in simulation.The result shows that the CPML can absorb the propagating modes,but also be highly effective at absorbing low-frequency evanescent modes.Its application prospect is displayed in simulating the EMP radiator. |
| Keywords: | finite-difference time-domain(FDTD) electromagnetic pulse(EMP) convolutional perfectly matched layer(CPML) modified perfectly matched layer(MPML) |
