In this letter, aperture efficiency of reflectarrays is enhanced using an efficient full-wave method. The full-wave method deals with the effect of real mutual coupling between all reflectarray elements exactly during its design process. Resultant long CPU time is greatly reduced by developing an efficient algorithm which is optimized for the vector supercomputer. Numerical simulation shows that the aperture efficiency of the reflectarrays can be enhanced using the proposed method. The proposed method is computationally efficient and applicable for various design targets.
