Verification of radiation pattern control using a cylindrical metasurface

We present transmission measurement results of a cylindrical impedance metasurface used to reshape the radiation pattern of an enclosed two-dimensional current line source. The metasurface was fabricated using printed circuit board methods and measured in a parallel plate waveguide. Measurement results are in agreement with the desired azimuthal image pattern, validating the design procedure of the cylindrical metasurface.
