Abstract The effective microwave refractive index (N_m) of traveling wave electrode is an important parameter in the designing of LiNbO₃ electro-optic modulator. A method for mea-kiring N_m is proposed in this paper. The probe frames, microwave probe and three kinds of sample CPW electrodes used in this method are designed and fabricated. The experimental results of N_min CPW traveling-wave electrode are given. Finally, the errors of the measurement are analyzed.
