proposed magneto-electric point scattering theory provides in how split rings scatter. In this section we will consider the eigenmodes and the radiation patterns of a single SRR for $\boldsymbol{\alpha}$ given by Eq. (\[Eq:SRRradiationdamp\]). Next, we predict which set of experiments will provide full information on the elements of the polarizability tensor. We will show how the extinction cross sections can be translated back to retrieve SRR polarizabilities and magneto-electric cross polarizabilities of a single SRR. Although the results we present are general, we use a specific set of parameters for all the figures presented in this paper. These parameters are chosen to fit to the properties of split rings that are resonant at $\lambda=1.5~\mu$m ($\omega_0/2\pi= 200$ THz and that consist of 200 by 200 nm gold split rings with a thickness of 30 nm and a gap width of 90 nm. Thus we take $V=200\times 200\times
30$ nm$^3$. We set the damping rate to be that of gold $\gamma
=1.25\cdot 10^{14}$ s$^{-1}$ as fitted to optical constants tabulated in in Ref. . We use $\eta_E=0.7$, $\eta_H=0.3$ and $\eta_C=0.4$. These parameters were chosen because (A) they reproduce quantitatively the extinction cross section under normal incidence along the $z$-axis measured by Husnik
