abstract = "It is well recognized that near-field effects become dominant when
the metamaterial (MM) is in resonance. In addition, any inaccurate
information of the location of reference planes, and the effective
length can seriously affect the accuracy of retrieved
electromagnetic properties of MMs. By considering all these
issues, in this research paper, we propose a retrieval method for
reference-plane invariant and thickness-independent determination
of electromagnetic parameters of MM slabs involving boundary
effects. Our method first accomplishes determination of effective
length of MMs and calibration-plane factors using scattering
parameter measurements, aside the resonance region, of two
identical MMs with different lengths. Our method then incorporates
near-field effects in accurate retrieval of electromagnetic
properties of MMs. The method is verified by scattering parameters
simulated for a homogeneous conventional material and a weakly or
negligibly coupled inhomogeneous MM slab made by two metallic
concentric split-ring-resonators. Consequences of an inaccurate
information of reference-plane transformation factors and the
value of effective lengths and of noninclusion of near field
effects on the retrieved electromagnetic properties are thoroughly
discussed by way of few examples to substantiate the accuracy of
the proposed method.",
