Electromagnetic Fields in a Dissipative Half-Space: A Numerical Approach

The electromagnetic fields of a source in a dissipative half-space are evaluated by a numerical technique. This report illustrates the application of the method to the case of the submerged horizontal electric dipole, but the method is applicable to horizontal or vertical dipoles located in either medium. The major advantage of this method is that it provides solutions for media and frequencies which were previously unavailable. In addition, this numerical solution can independently verify previously obtained asymptotic solutions and their regions of validity. Comparisons are included between numerical results and experimental measurements performed in the Atlantic Ocean.
