Abstract: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. Moreover, 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.
