Modeling the TDEM response for a lateral change in conductivity
The solution of the transient response of a layered earth excited by a vertical magnetic dipole is well known and used. Expansion of the solution for a 2D or 3D earth, where the conductivity changes in not just the z-direction, is extremely difficult and has only been done by way of numerical …

Multi-fold TDEM Experiment Design for Near Surface Conductivity Mapping
Multi-fold Time Domain Electromagnetics (TDEM) is a novel experimental approach that couples elements of traditional land-based TDEM survey designs to obtain a robust data set. This design inherently accommodates a broad range of possible Earth models through a rich combination of analysis …

Inversion strategies for seismic surface waves and time-domain electromagnetic data with application to geotechnical characterization examples.
… (SSW) data and the Time Domain Electromagnetic (TDEM) observations. The present work consists of two parts: (1) The first one is about possible implementations of the minimum gradient support stabilizer into a SSW inversion routine and its extension to the laterally constrained case. By means of …

Effects of wideband complex electromagnetic properties of soils on geophysical sensor performance, The
… such as time domain electromagnetic induction (TDEM) metal detectors and ground penetrating radar (GPR) suffer performance degradation as a function of site specific complex electromagnetic soil properties (permittivity, permeability and conductivity). Knowledge of these soil properties from the …
