A design method of refiectarray by the induced electromotive force method is proposed. The effect of oblique incidence from a primary source to a refiectarray element is included in the design process of the refiectarray by the proposed method. The CPU time for design of the refiectarray by the proposed method is small because mutual coupling between refiectarray elements are ignored. The refiectarray which consists of a dipole and parasitic dipole element is designed by the proposed method and the performance of the proposed method is shown.
