Electrical Method To Detect Objects In Sea Water

Analytical expressions, which help to calculate the electromagnetic field of the grounded wire with acceptable accuracy, were obtained based on a rigorous solution of the problem, it is shown that the field of a small electrode antenna is mainly determined by the field of free charges on the metallic electrodes, it is indicated that the electric field on big distances from the electrodes is represented as a superposition of the fields of point-sources, the calculation of the diffraction field of a conducting sphere, which is situated in the field of the grounded wire, was provided as an example.
