In this study, numerical analysis of scattering from a dielectric-coated metallic reflector is presented. The reflector has a parabolic cross-sectional cylindrical geometry. Radiation patterns and aperture efficiency parameters are analyzed using physical optics. A complex source point located at the focal point of the parabolic reflector is used as the source of radiation. The dielectric-coated metallic reflector is considered as an antenna, and an impedance boundary is utilized. The effects of coating on radiation patterns are analyzed in terms of dielectric thickness and dielectric permittivity. Numerical results are presented for various parameters, including dielectric permittivity, dielectric layer thickness, complex source point width, and focal distance.
