| Summary: | Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2001. === Over the last decade, as the mining industry of South Africa is moving
to ever deeper mines, the borehole radar is becoming an increasingly important
field of research.
In December 2000, Burger completed his thesis on Electromagnetic Modelling
of a Borehole Radar Environment with the FDTD Method. The
goal of this thesis is to extend the research presented in Burger's thesis,
considering how more advanced modelling techniques can be applied to
the FDTD analysis of the borehole radar environment.
Some of these techniques include implementation of dispersive and conductive
material models, and developing Uniaxial Perfectly Matched
Layer boundary conditions for matching these model. Simulations were
run to measure the performance of these boundary condition for matching
dispersive and conductive materials.
The thesis also includes the implementation of a parallel version of the
FDTD algorithm using the Message Passing Interface library.
Finally several realistic borehole models where simulated to test the accuracy
of the code and to show how the code can be used to model real
world problems.
