摘要
本文用技坐标系中的时域有限差分法(FD-TD)模拟了磁偶极子激励的脉冲电磁波在均匀和轴对称分层均匀损耗介质中的传播问题,所得结果与文献中对类似问题的研究结果一致,从而相互得到了验证。并进一步证明Maxwell方程完全适应于脉冲电磁波在损耗介质中的传播问题。所用方法可用于电磁脉冲测并问题的进一步研究。
In this paper, the propagtion of the electmpetic pulse excited by the magneticdipole in the uniform lossy mediun and axially symmetrical, layer uniform lossy medium is simulated byusing the Finite Different Time Domain(FD-TD) method of the cylindrical coordinates. The results areconsistent with those of the similar problems shown in the reference, so they mutually verify each otherand further prove that Maxwell equations are suitable for the propagation of the EM pulse wave in thelony medium. The method in this paper can be used for further study in the EM pulse logging problem.
