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.

DRBEM solutions of Stokes and Navier-Stokes equations in cavities under point source magnetic field Senel, P.; Tezer, Münevver (2016-03-01) This paper describes an iterative dual reciprocity boundary element method (DRBEM) for the solutions of Stokes and Navier-Stokes equations in cavities under the effect of an external point source magnetic field placed very close to the bottom. The fluid is viscous, incompressible and electrically non-conducting but magnetizable, and the flow is steady, laminar and fully developed. Both the Stokes and Navier-Stokes equations are solved in terms of velocity and pressure of the fluid by using DRBEM. Pressure b...
MOM analysis of loaded printed dipoles with applications in the design of electrically small antennas Batur, Mehmet Nazım; Alatan, Lale; Department of Electrical and Electronics Engineering (2015) Mixed Potential Integral Equation based Method of Moments (MoM) code is developed in MATLAB environment to analyze a loaded printed dipole antenna. Closed-form spatial domain Green's functions are used in the formulation. The developed code is utilized in the analyses of Electrically Small Antennas (ESAs). It is known that real part of the input impedance of an ESA is very low, whereas imaginary part is negative and high. The inductive loading method is used in order to overcome this problem. Effects of loa...
Derivation of green’s functions for spherically stratified media using an equivalent two port network model / Yeni, Burcu; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2015) Derivation of dyadic Green’s functions for a variety of geometries is a problem frequently faced in different fields of electromagnetics including the analysis and design of antennas, waveguides and resonators. In the case of spherically stratified antenna, waveguide or resonator structures, the analytical derivation process of dyadic Green’s functions is often extremely complex while numerical solutions comprise heavy workload. In this thesis, an equivalent two-port network model, which was first developed...

Numerically efficient analysis of slot-lines in multilayer media using closed form Green's functions Dural Ünver, Mevlüde Gülbin; Aksun, MI (1996-05-16) A numerically efficient technique for the analysis of slot-line geometries in multilayer media is presented using closed-form Green's functions in the spatial domain employed in conjunction with the Method of Moments (MoM). The computed equivalent magnetic current distribution on the slot is used to determine the power radiated by the slot and the input impedance. In power calculations, the spatial domain Green's functions are approximated as a power series of radial distance, and the integrals involving th...
