| 摘 要： | 用时域有限差分法分析了钢筋混凝土砖墙对电磁脉冲传播的影响。考虑到天线对时域脉冲的滤波效应,分析的传播脉冲信号是从一个宽带圆锥柱形天线上数值生成的。计算结果给出了钢筋混凝土砖墙对脉冲信号传播的影响,包括辐射天线产生的脉冲波形的畸变效应、脉冲穿透钢筋混凝土砖墙时的场型分布、墙面对入射脉冲峰值的反射效应以及反射和透射脉冲的波形。

| Abstract: | In this paper,the short path propagation of an electromagnetic pulse generated numerically from a wideband conical monopole antenna through reinforced concrete wall of buildings has been studied in the timedomain using the finite-difference time-domain(FDTD) method.Computational results demonstrated the effects of the reinforced concrete wall on pulse signal propagation including the pulse waveform distortion made of transmitting antenna,field distribution when pulse propagating through wall,reflection of pulse peak and pulse waveform reflected from and transmitted through reinforced concrete wall. |
