Free space microwave measurements are reported for a split ring and post type metamaterial which exhibits negative refraction in a frequency band between 13.5 and 14.5 GHz. Varying azimuthal angles and magnitudes are achieved by changing the polarization of the transmitter and receiver relative to each other and to the anisotropic axes of the material. The amplitude of the cross-polarized transmission has been measured at 50% of the co-polarization level. The maximum amplitude was achieved at a polarization angle of 20° relative to the initial polarization. This polarization conversion indicates there are other losses besides ohmic losses.
