In this paper the complex scattering amplitude functions of a small metamaterial spheroid particle is derived. The Mueller matrix for polarimetric bistatic scattering from a layer of random metamaterial small spheroids, such as dishes or needles, is constructed. Bistatic scattering of metamaterial and dielectric spheroids are numerically calculated. Linearly co-polarized backscattering coefficients hh, vv , and hh-vv are presented to show the dependence upon frequency. The co-polarized and cross-polarized backscattering coefficients and polarizability of a layer of non-uniformly oriented metamaterial spheroids under illumination of an elliptic polarized plane wave are numerically simulated. Effects of metamaterial parameters on scattering pattern and scattering mechanism are interpreted. Numerical results indicate that scattering of metamaterial particles is enhanced largely and appears apparent directivity. Meanwhile, polarized difference of hh-vv strongly varies with frequency due to constitutive dispersion of () and ().
