The interaction of electromagnetic waves and three-dimensional nonisotropic (uniaxial) wire medium metamaterials based on a transport model

Summary form only given. The transport model for the wire medium is introduced in (IEEE Trans. on Antennas and Propagation, v. 60, pp. 4219-4239, Sep. 2012) and basically defines an equivalent diffusion parameter (D) and a conductivity (or permittivity) for an isotropic wire medium satisfying the drift diffusion equation J^cond(r, ω)=σ(ω)E(r, ω)-D(ω)∇ρ^cond(r, ω) in which, J^cond, E, and ρ are homogenized conduction current, electric field, and charge inside the wire medium, respectively. Using this model we have shown previously that scattering problem formulations become simpler and less computationally intensive compared to other real-space methods. The validity of this homogenization method was confirmed for the isotropic wire medium sphere and was compared to the ABC method and the full wave simulation results in previous presentations (URSI 2012 meetings at Boulder and Chicago).
