Query: Illusion Mechanisms with Cylindrical Metasurfaces: A General Synthesis
  Approach   We explore the use of cylindrical metasurfaces in providing several illusion
mechanisms including scattering cancellation and creating fictitious line
sources. We present the general synthesis approach that leads to such phenomena
by modeling the metasurface with effective polarizability tensors and by
applying boundary conditions to connect the tangential components of the
desired fields to the required surface polarization current densities that
generate such fields. We then use these required surface polarizations to
obtain the effective polarizabilities for the synthesis of the metasurface. We
demonstrate the use of this general method for the synthesis of metasurfaces
that lead to scattering cancellation and illusion effects, and discuss
practical scenarios by using loaded dipole antennas to realize the discretized
polarization current densities. This study is the first fundamental step that
may lead to interesting electromagnetic applications, like stealth technology,
antenna synthesis, wireless power transfer, sensors, cylindrical absorbers,
etc.
