Electromagnetic fields generated by a horizontal static electro dipole beneath the sea surface
In the region near the submarine, the static electromagnetic field may be generated by the electro-chemic current. The knowledge about the distribution of the field in the region is very important for finding the submarine. In this paper, the excited source of the field is idealized as a horizontal static electro dipole, based on the integral expressions of field excited by a low frequency electro dipole in the conducting half-space, taking the limit of w→0, the integral expressions, of the field excited by the static electro dipole are obtained. These integral expressions related to Bessel-fanction may the simplified as a set of very simple analytical formula, and based on which the discussion is made and the space distribution of electromagnetic field is calculated.
