    © 2016 IEEE. A dipole-based simulation method is presented to study the effects of edges on finite metasurfaces. This technique can accurately account for the physical limitations associated with fabrication and thereby leads to high fidelity predictions needed in practical applications. Moreover, it establishes a platform to improve the metasurface design process, given the fact that no periodic boundary condition is required and the interaction between different meta-atoms within the surface is taken into account. This paper presents the initial results of using this technique for a finite lens, composed of split-ring-resonators. The dipole moments are found and the far-field is computed and compared with full-wave simulations.
