Borehole radar EM wave simulation for mining applications using a parallel implementation of the 3-D FDTD algorithm

A borehole radar is a high resolution electromagnetic (EM) sensor for detecting electrical discontinuities in<br>rock formations. Often the host rock medium through which the wave propagates as well as the target ore-body<br>have complex electromagnetic properties. Modelling EM wave propagation in 3-D can be used to better understand<br>the physics of observed responses. It can provide useful insight into the interpretation of real data sets, as well as<br>show the effects that drilling fluid (mud), water and air in the borehole will have on the coupling from the antenna<br>to the host rock medium.
