Abstract :
Formulas for extremely low frequency (ELF) electromagnetic fields generated in a sea of finite depth by a submerged horizontal electric dipole (HED) are derived based on an air-water-seafloor three-layer model. Field components in seawater are computed using numerical integration technique and Euler´s transform. The effects of frequency, sea depth, seabed conductivity and depth of submerged transmitting HED on the electromagnetic field distribution in a sea are studied, and substantive results are obtained.
