Surface Plasmon Polariton Resonance Excitation by Grating on the Metal Substrate

In present work the surface plasmon polariton resonance excitation by grating on the metal substrate has been researched. The peculiarities of the propagation and excitation of surface plasmon polariton waves on plane silver and gold surfaces using metallic and dielectric gratings were studied. It is shown that a strong magnetic field appears under resonance in structures with a silver and gold substrate at certain grating parameters. Therefore, it is appropriate to use such structures to study luminescence excited by magnetic-dipole interaction.
