| 摘 要： | 所讨论的电磁场频率介于传统的低频电磁法和雷达频率之间。在这个频率范围内,传导电流和位移电流都是不可忽略的。采用高密度采样算法计算水平层状磁偶线圈模型的电磁响应,通过对归一化的电磁响应在不同地电情况的模拟,比较分析了高频电磁场响应特征以及位移电流对高频电磁响应的贡献。

| Abstract: | The high-frequency electromagnetic system operated at frequencies between GPR and traditional low-frequency electromagnetic method,where both the conduct currents and displacement currents can not be neglected.Using the linear filtering algorithm with high density sampling to model the electromagnetic responses in a layered earth excited by a horizontal loop source,we calculate the normalized electromagnetic responses in different electrical parameters,and then analysis the high-frequency electromagnetic characteristics and the contributions to responses from displacement currents by contrasts. |

| Keywords: | high-frequency electromagnetic normalized responses displacement currents high density sampling |
