Polarimetric Scattering from a Layer of Spatially-Oriented Metamaterial Small Spheroids

摘要：

The complex scattering amplitude functions of a small metamaterial spheroid are derived under Rayleigh approximation. |fvv| and |fhh| of dielectric spheroid are symmetric along incident direction,while metamaterial spheroid along spheroid s axis. The Mueller matrix for polarimetric scattering of a layer of random metamaterial small spheroids is constructed. Compared with dispersive FR-4 spheroids,σhh and σvv of metamaterial vary remarkably with frequency due to constitutive dispersion of ε(ω) and μ(ω), and take a peak at its resonance frequency. The σhh and σvv and polarizability degreems, are simulated for a layer of nonuniformly oriented metamaterial spheroids under the illumination of an elliptically polarized plane wave. The scattering of metamaterial particles exhibits asymmetric directivity.
