Electromagnetic characteristics influence caused by wire cage replacing hollow conductor cylinder in hybrid simulator

  • 摘要: 主要关注空心导体圆柱的等效替代品-圆柱线栅笼的电磁特性,分别基于保角变换和等效电磁场理论进行了等效半径的推导,在此基础上运用电磁仿真软件CST仿真分析了金属线栅的疏密和粗细程度对测试区电场波形的上升沿、脉宽和峰值的影响,并且对比了圆柱线栅笼和空心导体圆柱两种结构的电场分布。分析结果显示,双锥笼型结构完全能够等效代替空心导体圆柱,且进一步验证了等效半径理论的正确性。
