The end-fire coupling technique has been used for generation, when the beam is focused on the metal–dielectric interface. It has been found that at normal beam incidence the efficiency of plasmon-polaritons generation is maximum and the half-width of the dependence of the generation efficiency on the angle of radiation incidence in the sample plane is 6.0° ± 0.5°. It is shown that the generation efficiency has a maximum at a certain shift of the center of the incident beam relative to the metal–dielectric interface.
