A periodic multilayer structure with metal and dielectric layers is proposed to obtain a broad stop-band filter. The influence of three factors（ the number of the metal layer（ n）,the metal layer and the dielectric layer）on the stop-band and central frequency of cross ring resonator（ CRR） filter has been investigated. Simulated results indicate that the stop-bandwidth can reach to 2. 2THz. M oreover,The stop-band and central frequency can be modulated by selecting appropriate n or dielectric layer,but it is not sensitive to the metal layer.
