With the SG structure, the dipole can effectively couple energy into an SP feature, which has a mixed nature of localized surface plasmon (LSP) and surface plasmon polariton (SPP). The SPP energy is confined by a grating structure with a well designed grating period and position. With such a cavity configuration, the SPP energy can be well preserved. Both the dipole-SP coupling behaviors in the frequency and time domains are numerically illustrated. The results are useful for designing a metal/dielectric interface nanostructure for implementing a SPASER (surface plasmon amplification by stimulated emission of radiation) system. © 2009 IOP Publishing Ltd.[SDGs]SDG7Cavity configurations; Coupling systems; Effective energies; Frequency and time domains; Grating periods; Grating structures; Light emitters; Localized surface plasmons; Metal nanostructures; Simulation results; Single grooves; Surface plasmon-polariton; Surface plasmons; Amplification; Density (specific gravity); Nanostructures; Plasmons; Surface plasmon resonance; metal; nanomaterial; article; dipole; electric potential; energy; energy conservation; energy transfer; light emitting diode; preservation; priority journal; radiation; surface plasmon resonance; algorithm; computer simulation; instrumentation; methodology; thermodynamics; Algorithms; Computer Simulation; Nanostructures; Surface Plasmon Resonance; Thermodynamicsjournal article10.1088/0957-4484/20/13/1352022-s2.0-65149096428WOS:000264093800004
