  In the last few years, non-homogeneous metasurfaces captured huge interest in tailoring electromagnetic waves, ranging from microwave to optical frequencies. Several technologies have been proposed, but a general design approach is still missing: the aim of this work is to present a modeling tool for the control of electromagnetic waves propagations. This approach enables to link the meta-surfaces electromagnetic properties with their geometrical and physical characteristics. To validate the proposed approach, two different applications will be reported: a flat Luneburg Lens and a sharp corner guiding structure. Results show good performance in terms of wide bandwidth and source independence.
