Prof. Dr. Faruk KARADAĞIt is necessary to investigate the scattering of electromagnetic waves fromvarious geometries and the effects of these geometries to scattering and radiation foranalysis and synthesis of the electromagnetic scatterers and sources. In this study,scattering from an inhomogeneous canonical structure is investigated. Scatteringfrom a spherical structure is a canonical problem. Finite difference time domain(FDTD) will be used as the numerical method for the solution of the problem. Thescattered field from the sphere will be determined in the specified space and after forobtaining the field expressions outside this space perfectly matched layer (PML) willbe used for the boundary condition.Key Words: FDTD, Numeric, Sphere, ScatteringI
