The transmission of a terahertz electromagnetic wave of the transverse magnetic polarization through a 1D photonic crystal of finite thickness containing a defect is theoretically studied. The defect is a plate of the layered superconductor with the superconducting layers orthogonal to the layers of the photonic crystal. An analytical expression for the transmission coefficient is derived. We show that the transparency in the band gap of the photonic crystal can be significantly enhanced due to the resonant excitation of the eigenmodes localized near the defect.
