摘要：

We examine the propagation of plasmonic TM (Transverse Modes) modes generated in the designed periodic array of silver (Ag) embedded on silicon (Si) substrate. The properties of surface plasmons are tailored by altering the size of Ag nanorods and its periodicity. Conventional waveguides cannot guide electromagnetic energy below the diffraction limit of light, which can be overcome by texturing the metal or dielectric surface. In this hybrid design we have textured the interface by placing metallic, Ag nanorods on Si substrate placed over bilayer system of glasses. This provides the missing momentum required, since SPP modes always lay beyond the light line and has shown strong confinement of light. Ag nanorods are structured at nano dimensions to control and manipulate surface plasmon polariton (SPP) propagation and thus open new possibilities in light matter interaction.
