Abstract Details

2014, Master of Science, University of Akron, Electrical Engineering.
The work presented in this thesis deals with the behavior of the scattered electromagnetic eld on the surface of the scatterer. Namely, our goal is to nd the normal derivative of the eld numerically for applications such as the calculation of the radar cross-section or surface current. The phenomenon is addressed through the resolution of a wave problem with boundary conditions speci ed using a sequence of local operators. We consider the two dimensional problem with an arbitrary-shaped scatterer made in a material assumed perfectly conducting. At rst, we introduce the main theoretical ideas and concepts that will serve our work and that have inspired it; this prceeds from the mathematical formulation of the solutions, to the solving procedures and through the expression of the boundary conditions. In a second part, a method to nd exact solutions will be presented for comparison purpose. The solutions thus found will be later compared to the results obtained from our numerical procedures. These procedures are presented in detail in the third and fourth chapters, they include a brute-force method and a Laplacetransform based method. Finally, the results are presented, discussed and a statement of the method performance will be set. Figures are included to illustrate our views.
