| 摘 要： | 当偶极子源(电偶极子或磁偶极子)置于多层环状导电媒质中偏离轴线的任意一点时,所激发的电磁场既存在TE波又存在TM波。文中导出了各层媒质中电磁场的通解,用边界条件建立了系数传递矩阵,从而完全确定了电磁场表达式。计算实例中给出了一组离轴偶极子的响应曲线。

| Abstract: | When a dipole source (electric dipole or magnetic dipole) is located at arbitrary point in circularly multilayered conductive medium, the electromagnetic fields excited by the source contain both TE and TM waves. The series solutions of the fields in every layer are derived analytically in this paper. A coefficient recurrence matrix is established by means of the boundary conditions. In such way, the expressions of fields can be determined definitely. As a numerical example, a group of response curves of an off-axis source are given finally. |
