A metamaterial parabolic tap design is proposed and investigated; the tap has a metamaterial filling, it is designed for producing an efficient tapping where the subwavelength focusing exists. The design shows a high efficiency (power/physical dimensions) compared to a metamaterial rectangular tap design and to a natural material parabolic design. For comparison, the natural material parabolic design provides only 1% of the guided power while the output of the metamaterial parabolic design is 26%. For the same length and depth, the metamaterial rectangular tap design produces 8%. Moreover, it is noticed that the scattering around the tap is significantly low.
