  We report the experimental verification of metamaterial cloaking for a 3D
object in free space. We apply the plasmonic cloaking technique, based on
scattering cancellation, to suppress microwave scattering from a finite-length
dielectric cylinder. We verify that scattering suppression is obtained all
around the object in the near- and far-field and for different incidence
angles, validating our measurements with analytical results and full-wave
simulations. Our near-field and far-field measurements confirm that realistic
and robust plasmonic metamaterial cloaks may be realized for elongated 3D
objects with moderate transverse cross-section at microwave frequencies.
