Electromagnetic waves transmission at THz in superconducting nano-photonic crystsls containing metamaterials has been theoretically investigated based on the transfer matrix method together with two-fluid model. The results show the existence of a cutoff frequency in such structures. Electromagnetic wave is allowed to propagate through the structure when its frequency is higher than cutoff frequency. We studied the effect of some parameters of metamaterials such as the thicknesses and electric permeability coefficient. It is seen that this cutoff frequency can be efficiently tuned dependent on thicknesse of metamaterials, and the operating temperature as well. These structures can be useful in design of optoelectronic devices.
