description Surface Polariton dispersion is demonstrated in the interface of two mediums and thin slab. Starting from 4 Maxwell equations, dispersion equations for s-polarization and p-polarisation are derived. Solutions of the tangential dispersion relation and normal dispersion relation for s-polarization is completely symmetrical to that of the p-polarization, due to the symmetry between the electric and magnetic responses in the Maxwell equations. If the materials are both dielectric and magnetic, mi ; ei 6=1, the s-polarized light can also excite the propagating surface modes, not just the p-polarized light. Analysis reveals additional new regimes of surface polariton resonances with magnetic materials for both polarizations. Coexistence of the dielectric dispersion in e2(w) and the magnetic dispersion in m2(w) give rise to the second peaks in the spectra of kx for s and p polarizations. By considering damping, large wavevector in large frequency range can be achieved if SP is excited at the interface where medium 1 is a dispersive medium and medium 2 is also a dispersive medium which contains a slightly different permittivity or permeability. SP modes in thin metamaterial slab are analysed. In such a system, each single interface can sustain bound SP. When the separation between adjacent interfaces is smaller than the decay length, interactions between SP at both interface give rise to coupled modes, odd mode and even mode. Dispersions of SP in thin slab are solved numerically. Similar to one dimensional solution, s-polarized wave can also excite propagating surface modes. Considering damping and without damping, dispersion curves are drawn for both modes with reducing slab thickness. Noticed that resonant happens at resonance frequency when m1 =
