On a new class of $S$-polarized surface polaritons at the interface between two media with saturated nonlinearity

It has been shown that $S$-polarized surface polaritons can propagate along the interface between two media with saturated nonlinearity. The profile of the wave amplitude has a maximum in one of the contacting media. An expression has been obtained for the wave field amplitude at the interface. The relation between the surface wave vector and wave frequency can be arbitrary.
