   Abstract:
   The phenomenology of frequency- and time-domain electromagnetic induction (EMI) is examined in detail, through use of a rigorous electromagnetic scattering model, and through appropriate signal analysis. We demonstrate that both the time- and frequency-domain EMI signatures can be characterized in terms of a few magnetic singularities, thereby significantly reducing the number of features that need be stored for target identification. Further, we examine the aspect-dependent properties of the relative excitation strengths of the magnetic-singularity modes. Finally, we perform a statistical analysis of the relative efficacy of frequency- and time-domain EMI operation, for a class of conducting targets.
