摘要
对于包含n层线性、均匀、各向同性的水平成层导电介质,本文应用汉克尔变换及其逆变换推导求得了位于顶层导电媒质中的时谐垂直电偶极子在该层产生的电磁场的表达通式.通过这些表达式能够很方便地求得包含任意多层导体半空间中的电磁场.文中最后计算了导电半体空间和二层导电介质中时谐垂直电偶极子产生的电磁场,验正了本文所得结果的正确性.
A series of general expressions of electromagnetic field of a vertical electric dipole (VED), harmonic time varying, embedded in surface of the first conducting medium of a stratified medium composed of n, linear, homogeneous conducting layers, is presented by applying the zero-order Hankel transform and its inverse transform. The electromagnetic field of a stratified medium which include any number of conducting layers can be obtained conveniently by means of these expressions.
