摘要
本文从电磁场基本方程出发引入标量函数F,讨论了磁偶极源激发下导电半空间瞬变电磁场的传播规律,从理论上证明了“烟圈”效应的存在性,得到了一些有益的结论。
In this paper the travelling law of the quasi-static transient electromagnetic field excited by a vertical magnetic dipole in a conducting half-space is discussed, making use of the scalar function F derived from the basic electromagnetic equations. The existance of the current filament effect is demonstrated theoretically. Some useful conclusions are obtained.
