In-plane (parallel) and off-plane (orthogonal) surface plasmon polaritons at the interfaces between the dielectric and thin metallic film was studied. For the half-space (planar) geometry with ordinary in-plane surface plasmon polariton modes, the Kretschmann or Otto configurations are needed to create surface plasmons. In the case of thin metallic films with the thickness much smaller than the wave-length of excited laser beam, there are two modes of surface plasmon polaritons appeared: in-plane and off-plane. The off-plane surface plasmon polaritons do not need the additional configurations as in-plane case, and has weak dependence on the incident angle. In this work a possible application of off-plane for design optical cold atom traps was considered.
