Mj. Flykt et al., DC POTENTIAL ANOMALIES CAUSED BY A CONDUCTING BODY IN AN ANISOTROPIC CONDUCTING HALF-SPACE, IEEE transactions on geoscience and remote sensing, 34(1), 1996, pp. 27-32
Image theory for dc problems involving a current source in an anisotro
pic half-space bounded by either a perfectly magnetically conducting (
PMC) or electrically conducting (PEC) plane is being used to get the s
olution for the potential in integral form, A dipole approximation for
a small sphere is developed.
