Abstract:In this thesis, partial differential equation techniques for solving the problem of electromagnetic scattering by a three-dimensional body of revolution are discussed. The unknowns used do not obey the scalar Helmholtz equation. Thus, neither the Mur nor the Bayliss-Turkel boundary condition can be used. Therefore, a boundary condition derived from Wilcox's expansion for the scattered fields is employed. This is done for both finite difference and finite element meshes having either cylindrical or spherical outer boundaries. The question of reformulating the problem in terms of unknowns with relatively slow spatial variation is also considered.
