    Traditional optical devices cannot meet the requirements of modern optical integration because of their bulky size and sensitivity to linearly polarized light or circularly polarized light. In this paper, based on surface plasmon polaritons (SPPs), a universal polarization analyzer consisting of catenary was designed. The theory of SPPs propagation was derived, and the electric field pattern of catenary and the distribution of electric field intensity in the center of the device were calculated by using the finite difference time domain method. The results show that when light of different polarization states are incident separately, catenary has a variety of electric field patterns. The significantly differentiated electric field distribution in the center of the device can effectively distinguish the polarization states of linearly polarized light, circular polarized light and vector polarized light (radial polarized light and angular polarized light). Therefore, these results are helpful for the research and development of the catenary multifunctional devices.
