Abstract
KHERNER3 is a program written in FORTRAN 77 for the computation of extremely low frequency (ELF) electromagnetic fields from an electric dipole source. The electric source is located in the upper layer of a two-layer conducting half-space. In a marine environment, this model corresponds to a single semi-infinite conducting seabed. For a better modeling of electromagnetic propagation in shallow water, the program was modified to accept an arbitrary number of conducting layers. A multi-layer structure translates into a correction factor for the conductivity of the bottom layer in the previous two-layer conducting half-space model. The correction is a function of the (complex) incidence angle and it was introduced directly in the numerical integration of 1-D field integrals in the wave number region.
