Bob Grimm - TD3D
Time-Domain Three-Dimensional Modeling of the Electromagnetic Response of a Triaxial Object

Tom Sprott implemented this model and graphical user interface based on our research. Its application to a seeded test bed showed that elongated (UXO-like) objects could be reliably discriminated from flattened (scrap-like) objects.

Example TD3D model calculation and fit to data. Note sign reversal of Y-component. Data acquired with an orange box.
