超宽带电磁脉冲辐射传播特性研究

A study about the radiation propagation property of UWB electromagnetic pulse

研究在圆盘辐射器条件下,对两种经归一化处理后的典型脉冲,根据电磁场理论,给出它们轴线能量传播特性的解析计算公式与数值模拟结果,并给出其中矩形脉冲的超宽带电磁能量传播趋势的三维模拟。模拟结果证明,超宽带电磁脉冲能量在不同传播区段表现出不衰减、慢衰减等特征。

With the radiating antenna, this paper discusses the analytical and numerical results of axial energy of two typical waveform pulse normalized by electromagnetic theory. Finally, it images 3D stimulation of the UWB electromagnetic energy of the rectangle pulse. The results indicate that the UWB electromagnetic energy has the characters of un-attenuating or slow decaying in different transmitting domains.
