摘要
将海水看作线性、均匀、各向同性的半无限大导体空间 ,利用汉克尔变换及开尔文函数的近似展开式 ,推导求得了极低频时谐水平电偶极子在海水中产生的电磁场的近似解析表达式。运用推导的解析表达式 ,可以计算海水中任意场点的电磁场值。
By applying the Hankel transform and the polynomial approximate expression of Kelvin functions, the analytical expressions of the electromagnetic fields were presented for a extremely low frequency (ELF), time-harmonic, horizontal electric dipole (HED) embedded in the sea. The sea water is considered as a uniform conducting half-space media. The electromagnetic fields at arbitrary sea water depth can be calculated by those expressions given in the paper.
