Research on metasurfaces has been widespread recently because it can generate arbitrary permittivity and permeability which can be used to synthesize different types of flat surface-wave based lens for engineering applications such as nanofocusing, sensing, detection, and spectral imaging. In this paper, we use the periodic array of square metallic patches etched over a thin grounded dielectric sheet to synthesize a flat Mikaelian lens of rectangular shape that is narrower than contemporary circularly-shaped lens. The design is validated by simulation results, which demonstrate the effectiveness of the focusing.
