The Integral-Equation Method in Low-Frequency Electrodynamics of Nonhomogeneous Contrast Media

Resumo

The article analyzes computations of low-frequency electrodynamic fields in a nonhomogeneous conducting medium using the integral equation method. Contrast effects arise when the nonhomogeneities are embedded in a low-conductivity medium. As the conductivity of the enclosing medium decreases, tighter grid spacing is required in the nonhomogeneous region.
