The two-dimensional planar hyperbolic reflector, which is designed with coordinate transformation method, shows the same scattering characteristic as the hyperbolic reflector while maintains a flat structure. In this paper, the scattering performance of the planar hyperbolic reflector is simulated and the distributions along each direction of the required rectangle metamaterials are given. The variations of each constitutive parameter extremum and the normalized distributions of the required rectangle metamaterials are further analyzed with different eccentricies of the hyperbolic reflectors, which can provide some guidance and suggestions for the practical fabrication work.
