Simulation of electromagnetic induction scattering from targets with negligible to moderate penetration by primary fields
TLDR
The problem of numerical modeling of electromagnetic induction (EMI) responses by metallic objects is complicated by the fact that transmitted fields may penetrate the target, but will often only do so slightly. Expand
