Özet:

In this thesis a structure with thin wire attached to a PEC plate is analyzed numerically by using Method of Moments (MoM) with Galerkin’s testing scheme. The structure is divided into two parts: the plate and the thin wire and each part is analyzed separately. The RWG basis functions are chosen as basis/testing functions for the plate, piecewise linear basis/testing function is chosen for the thin wire and an attachment mode basis function that is compatible with RWG and piecewise linear basis functions is applied at the junction. To overcome the singularity problem that occurs during the computation of MoM matrix entries, different singularity handling methods are used and the obtained results are presented. First, scattering from a conducting plate and a conducting wire are analyzed separately. Then these two structures are combined in a non-contacting configuration and this combined structure is analyzed by incorporating the interaction between the wire and the plate. Finally, these two structures are combined in a contacting configuration and analyzed by making use of an attachment current at the contact point.
