| 摘 要： | 利用电子流体力学方程和麦克斯韦方程组可对高功率微波(HPM)脉冲传输的物理过程进行数值模拟。在此基础上根据能量守恒原理进行改进,提出一种新的改进模型,可有效地减少计算量。数值计算表明,改进模型所得模拟结果与原模型的结果吻合较好。

| Abstract: | It is feasible to simulate the physical process of high power microwave propagation in air by applying electron fluid equations and Maxwell's equations.However,this model will require extensive computer time for simulation characteristic of high power microwave long pulse propagation.In this paper,we present a new refined model which requires less computational complexity for simulation characteristic of high power microwave long pulse according to conservation of energy.Numerical simulation shows good agreement between the envelopes of the two models. |

| Keywords: | high power microwave propagation in air refined model finite difference method |
