![]() | Vardeny, Zeev Valentine; Nahata, Ajay | Midinfrared optical response and thermal emission from plasmonic lattices on Al films | We studied the midinfrared optical transmission and thermal light emission spectra of subwavelength hole arrays in the form of square lattice with 4 µm periodicity (plasmonic lattice) in aluminum films deposited on silicon substrates. The optical transmission of these films showed temperature inde... | Plasmonic lattices; Midinfrared optical response; Thermal emission; Surface plasmon polaritons; Anomalous transmission; Extraordinary optical transmission; EOT | 2007-11 |

![]() | Vardeny, Zeev Valentine; Nahata, Ajay | THz anomalous transmission in plasmonic lattices; incidence angle dependence | The phenomenon of anomalous transmission through subwavelength aperture arrays in metallic films (plasmonic lattices) is thought to be mediated by surface plasmon polaritons (SPP) on the film surfaces. Using terahertz time-domain spectroscopy we systematically studied the anomalous transmission spec... | THz anomalous transmission; Plasmonic lattices; Incidence angle dependence; THz radiation; Light polarization; Effective dielectric response; Notch filter | 2009 |

![]() | Vardeny, Zeev Valentine | Ultrafast response of surface electromagnetic waves in an aluminum film perforated with subwavelength hole arrays | The ultrafast dynamics of surface electromagnetic waves photogenerated on aluminum film perforated with subwavelength arrays of holes was studied in the visible spectral range by the technique of transient photomodulation with ~100 fs time resolution. We observed a pronounced blueshift of the resona... | Subwavelength hole arrays; Nanohole arrays; Transient photomodulation; Plasmonic lattices; Surface electromagnetic waves; SEW; Periodic subwavelength arrays | 2008-02 |
