| 摘 要： | 在3维Yee网格模型以及蛙跳模型的基础上，分析了3维电磁场离散算法及其稳定条件，讨论了3维空间网格上电磁场作用于粒子的平均场权重法和粒子作用于电磁场的Charge-conserving法，同时也讨论了3维空间网格上理想导体边界条件、自由吸收边界条件、爆炸式发射模型的模拟实现方法。以向内发射同轴二极管为例从其电流电压关系及电子束运动特性方面验证了模拟的正确性。

| Abstract: | A 3D electromagnetic field algorithm and the stability condition of the electromagnetic were analyzed based on the 3D Yee grid model and the leapfrog model.The average-weighting and chargeconserving ways to realize the interaction between electromagnetic and particles were discussed.At the same time the perfect conductor boundary condition,the free space absorbing boundary and explosive emission model were discussed.Finally,inward-emitting coaxial diode was used as an example to validate the simulation of current-voltage correlation and characteristics of electron beam movement. |
