摘　　要：以馈电脉冲为高斯脉冲为例,对瞬态电磁脉冲能量传输特性进行了简洁的理论解释和实验验证。首先以圆形电流辐射单元为例讨论其能量传输的三段式规律及验证,对圆形电流在远场处的辐射能量进行分析,辐射源可以看作点辐射源;其次以点辐射单元为前提研究并验证阵列辐射单元的三段式传输规律。瞬态电磁脉冲能量传输特性由多列瞬态电磁波的叠加造成,不是麦克斯韦方程存在光子解的结果。The energy transmission characteristic of transient electromagnetic pulses is analysed and verified when Gaussian pulses are fed to antennas.The uniformly distributed circular current is simplified as a point radiation source according to the analysis and verification of energy transmission characteristic when far field of antenna is studied.On basis of this simplification for radiation source,the analysis and verification of energy transmission characteristic with arrayed elements have been completed.Transmission energy along z axis comes from superposition of transient electromagnetic waves rather than photon quantum characteristic of Maxwell equations for radiation sources.
