Modulated tensorial metasurfaces for aperture field generation

This paper presents a procedure for generating radiating aperture fields using tensorial metasurfaces. The aperture field is generated using surface wave to leaky wave conversion resulting from metasurface modulation. Amplitude and phase control are achieved using varying modulation parameters and holography principle respectively. In order to validate the design procedure, a numerical solution is presented for a multi-beam metasurface antenna working at 20GHz.
