Low-Frequency Subsurface Electromagnetic Modeling

Subsurface electromagnetic (EM) methods are applied to obtain underground information that is not available from surface observations. This research develops numerical methods for subsurface electromagnetic modeling. The dissertation includes: (1) fast one-dimensional forward and inverse modeling, which are commonly used in the oil industry, (2) a fast volume integral equation method, which is used to study the electromagnetic wave propagation in axisymmetric inhomogeneous media, and (3) a systematic approach to solving low-frequency scattering problems using the method of moments (MOM). These methods provide important modeling tools for the subsurface exploration.
