Measured Polarization Response of Negative Index Metamaterial
Abstract
The geometrical anisotropy and bi-anisotropy of a split ring and post type metamaterial is studied by free space microwave measurements in a frequency band near 13.5 GHz where it exhibits negative index of refraction. The orientation of the linearly polarized incident wave determines whether the refracted response is negative or positive. Measurements of cross polarization through the prism are 50% of the co-polarization. The insertion loss through the material of 3.36 dB/cm at 13.5 GHz, where the index n = -1, is therefore composed of both scattering and absorptive losses.
