Abstract: | We found an exact solution of Maxwell's equations, which describes the propagation ofp-polarized nonlinear surface polaritons and ofp-polarized nonlinear guided wave polaritons in two cases:i) in a film of a surface active material placed on a substrate described by a diagonal dielectric tensor whose elements depend on the amplitude of the electric field according to 1 1= 2 2=![epsi](/content/gg23236551w34450/xxlarge949.gif) + (|E

2|2), 3 3=![epsi](/content/gg23236551w34450/xxlarge949.gif) , andii) in a film described by the same dielectric tensor (optically uniaxial nonlinear crystal) placed on a substrate with dielectric constant 3 (optically linear medium). The power carried in the surface waves has also been exactly calculated. |
