The reflection and transmission of the terahertz electromagnetic waves propagating in the waveguide, through a sample of a layered superconductor of a finite length are studied theoretically. The excitation of two types of the Josephson plasma waves, ordinary and extraordinary, in the sample leads to a partial or a complete transformation of the incident wave polarization. The conditions of the complete transformation of polarization are found.
