We report a way to realize a left-handed metamaterial based on hybridization of trapped modes. This results from the stacking of two identical structures. The introduction of a structural asymmetry tunes the trapped modes without modifying Coulomb interactions. The negative index band is obtained thanks to the overlapping of two hybrid modes coming from two different modes. This approach is validated numerically and experimentally.
