This paper presents experimental results of measurements of near electric field in free space for a structure composed of periodic ring resonators. Simulation results performed using electromagnetic full-wave software show good agreement with the experiment results. Our results demonstrate that in a specific frequency band, a negative index behavior,supported by a backward-wave phenomenon, is present. This result confirms that in bianisotropic medium the magnetoelectric coupling can modify the well-known relation of index of refraction.
