1. An antenna system, comprising:

  • an antenna controller configured to operably couple to control inputs of an array of electromagnetic (EM) scattering elements having sub-wavelength spacing, the antenna controller configured to;

    control the array of EM scattering elements, through the control inputs, to operate according to modulation patterns;

    determine a performance parameter of the antenna system for a plurality of different combinations of different spatial holographic phases and effective mode indices, each of the plurality of different combinations having a different one of the modulation patterns corresponding thereto; and

    select one of the modulation patterns based, at least in part, on the performance parameter corresponding thereto.
