The Electromagnetic Field of a Horizontal and Time-Harmonic Dipole in a Two-Layer Medium

摘要

To investigate the modeling of Shaft-Rate Electric Field, the analytic expressions of the electromagnetic fields of time-harmonic, horizontal electric dipole (HED) embedded in the sea have been derived by using image method according to uniqueness theorem of the electromagnetic field with two layer model. The distribution of electromagnetic field produced by a horizontal electric dipole embedded in seawater has been numerically calculated and analyzed by applying fast Hanker transform and fast Fourier transform. Then the case of shallow sea and harmonic electric dipole has been simulated in laboratory and the experimental results are accorded with the simulation results, thus the correctness of the solution and the derivation are validated. The electromagnetic field of a horizontal and time-harmonic dipole is put in a two-layer medium.
