Electromagnetic analysis of a tangent-ogive dielectric radome with a metallic cap

In this paper, we analyze the electromagnetic characteristic of a tangent-ogive dielectric radome with a metallic cap based on the ray tracing and physical optics. We assume that point sources are located arbitrarily in a dielectric radome. Radiation pattern of the radome with a metallic cap-enclosed point sources is calculated to illustrate the electromagnetic characteristic of the radome.
