Abstract


In this paper, a polarizability matrix retrieval method for
bianisotropic metamaterials is introduced. By assuming that
scatterers can be modeled by equivalent point-dipoles located at
their centers, the induced dipole moments are analytically related
to the incident field. Using transmission line models, the
scattered fields are obtained for two individual cases of normal
wave incidence. These fields can be, finally, combined with the
incident field to produce the desired polarizability matrix in
terms of the measured or simulated scattering parameters.
