Scattering waves by a cylindrical conductive surface

Scattering of electromagnetic waves is the process by which electromagnetic waves change direction or frequency when interacting with a surface. This scattering event occurs as a result of the surface reflected or diffracted electromagnetic waves. In this thesis, the scattering of electromagnetic waves on a conductive cylindrical surface is discussed. The scattering of electromagnetic waves is usually analyzed using Maxwell's equations. The Maxwell's equations set up relations between the electric field and magnetic field. It provides mathematical modeling of phenomena such as electromagnetic wave propagation and scattering. First, these electromagnetic waves are modeled based on Maxwell's equations. Appropriate equations expressing the electric field and magnetic field at the surface of the cylinder are used. Then, the far-field approach is used. However, the far-field approach is valid in cases where the wavelength ratio of the distance to the observation point of the scattered electromagnetic waves is large enough. The far-field approach; It usually analyzes the parameters of the scattering event, such as scattering cross section, propagation angle, and scattered wave density. These parameters are used to determine the properties of the scattered wave. In this thesis, the behavior of the scattered fields from a cylindrical surface is analyzed in theory, and simulation with MATLAB. Then, the results are compared with Ansys HFSS software.
