Study Results from Southeast University in the Area of Plasmonics Reported

By a News Reporter-Staff News Editor at Physics Week -- Researchers detail new data in Plasmonics. According to news reporting originating in Jiangsu, People's Republic of China, by VerticalNews journalists, research stated, "A simple T-shaped plasmonic nanostructure composed of two perpendicular coupled nanorods is proposed to produce strong Fano resonances. By the near-field coupling between the 'bright' dipole and 'dark' quadrupole plasmons of the nanorods, a deep Fano dip is formed in the extinction spectrum, which can be well fitted by the Fano interference model."

The news reporters obtained a quote from the research from Southeast University, "The effects of the geometry parameters including nanorod length, coupling gap size, and coupling location to the Fano resonances are analyzed in detail, and a very high refractive index sensitivity is achieved by the Fano resonance. Also by adjusting the incident polarization direction, double Fano resonances can be formed by the interferences of the dipole, quadrupole, and hexapole plasmons. The proposed nanorod dimer structure is agile, and a trimer which supports double Fano resonances can be easily formed by introducing a third perpendicular coupled nanorod."

According to the news reporters, the research concluded: "The proposed T-shaped nanorod dimer structure may have applications in the fields of biological sensing and plasmon-induced transparency."
