Analysis and synthesis of fields in modulated metasurfaces

This paper concerns the analysis of fields and currents on modulated metasurfaces (MTSs) and the synthesis of MTSs implementing a given field distribution. The work herein described has been developed to set up an effective design process for modulated MTSs realizing antennas with customizable pattern. Here we give a brief description of the process for the analysis, synthesis and implementation of fields in modulated MTSs in the framework of planar leaky wave antennas. As support to the discussion, numerical results are presented for highly directive beam antennas.
