A planar metamaterial structure using liquid crystals sandwiched between layers of split ring resonators is demonstrated. This optimized structure has tunable negative index of refractive on account of a controlled permittivity of the liquid crystals drived by extend field The frequency range with negative index of refractive can be adjusted conveniently and reversibly. Numerical simulation and analyzation show this is a valid metamaterial structure.
