Abstract

The time-harmonic electric dipole itself can directly simulate some field sources. And for some complex field sources, they can also be described by superposition of electric dipoles. In the deep sea, the influence of the seabed is often ignored. When solving the magnetic field generated by an electric dipole, the sea-air model is adopted. Firstly, the magnetic vector potential is solved from Maxwell’s equation with the boundary conditions. Secondly, the expression of the electric field is derived by means of image method. Finally, the analytical solution is obtained by the numerical method. The simulation results show that magnetic fields generated by the time-harmonic electric dipole have strong regional character and decrease quickly with the increase of the distance.
