In recent years, composite right left hand transmission line (CRLH-TL) metamaterials have been the subject of research interest for many applications. In this paper, a simple and efficient genetic algorithm method is adopted for tuning the LC-parameters of composite right-left hand transmission line (CRLH-TL) metamaterial unit cell. The genetic algorithm is used with the pseudo-inverse method to get optimum solutions of the LC-parameters. Two different designs are implemented to evaluate the proposed algorithm for composite right-left hand transmission line metamaterial unit cell. The first design represents symmetric T-network at the frequency of 10 GHz, and the second design represents symmetric π network at the frequency of 5.5 GHz. In this work we report exactly balanced designs obtained with simple computations.
