PROJECT TITLE :

Bi-anisotropic Metamaterials Effective Constitutive Parameters Extraction Using Oblique Incidence S-Parameters Method

ABSTRACT:

The S-parameters method for bi-anisotropic metamaterials effective constitutive parameters extraction is extended to oblique incidence. The proposed methodology permits to extract all unknown parameters using S-parameters measured over one metamaterial slab. The bi-anisotropic metamaterial may be a pseudochiral omega medium and assumed to own diagonal permittivity and permeability tensors. The extraction method steered involves each analytical extraction equations and numerical optimization. This methodology is utilized to indicate the limited validity of the idea of absence of spatial dispersion on which the proposed approach is based. The extraction technique is demonstrated over bulk and artificial media such as SRR metamaterial and therefore the results are validated with satisfactory agreement published data in the literature.
