摘要：

The electromagnetic scattering by a cylindrical Luneberg lens with a conducting reflector is analyzed by using the point matching method. The high accuracy of the point matching method is obtained from the convergence property of the total scattering cross-section versus matrix size. It is found that the scattering pattern has a backscattered field approximately several times that of a circular cylinder of the same radius. The radar cross-section versus incident angle is illustrated, whose figure has the relatively wide conical viewing angles. It is also found that the radar cross-section becomes relatively large as the radius of the cylinder increases.
