Total internal diffraction of plasmon surface polariton fields by a dielectric phase grating is described. The grating was fabricated by partly desorbing thin organic multilayers deposited on top of the plasmon-carrying Ag-air interface through the regularly spaced holes of an electron microscope grid. The diffraction pattern shows for various angles of incidence a characteristic intensity distribution which can be understood taking into account a grating wave vector mediated coupling of the two plasmons corresponding to the two different layer structures.
