垂直电偶极子在3层媒质中激发的电磁场
Electromagnetic Field of a Vertical Electric Dipole in Three-Layered Media
【摘要】 将地震前兆电磁源看成谐变垂直电偶极子,把地面以下视为2层分别均匀各向同性的有耗散线性媒质,采用对赫兹势作柱面波展开的方法求解麦克斯韦方程组,从而得出地下垂直电耦极子在各层媒质中激发的电磁场的积分形式解.
【Abstract】 A time-harmonic vertical electric dipole under the ground is assumed to be the warning electromagnetic source before a seism,and the earth is considered to be two-layered dissipative linear medium.Solving Maxmell’s equations by means of expanding Hertz-vector potential into Fourier-Bessel integral.the formal solutions of electromagnetic field generated a vertical electric dipole are derived,respectively,in three-layered region.
