针对普通并行算法的缺点,给出了连接体与分段建模的基本理论,提出了一种基于分段建模、系统整体模拟的并行电磁模拟计算方法,基于FDTD-PIC方法和消息传递机制在CHIPIC软件中实现了这一算法.并通过一个磁绝线振荡器加天线的简单系统验证了分段建模和解析的正确性,并通过对其的模拟和调试得到了天线系统输出的最大的功率6.2 GW,证实了此算法的可行性.%The theory of the connector and the subsection modeling was propounded. For the disadvantages of the magnetically insulated line oscillator (MILO) and antenna designed separately, a kind of system simulation method was proposed, and was completed by using finite-difference time-domain and particle-in-cell algorithm and message passing interface. In the simulation, a phenomenon was found that a amount of power from the antenna reflected into MILO, and the effective method to reduce the impact of reflected power was got. Results show that metal strut rods could filter out DC power, and the maxium output power of the antenna is 6. 2 GW, which also proves the validity of the method.
