Surface plasmon polaritons (SPPs) may serve as ultimate data processing expedients in future nanophotonic applications. SPPs combine the high localization of electrons with the bandwidth, frequency and propagation properties of photons, thus supplying nature with the best of two worlds. However, although plasmonics have recently gained constantly growing(More)
The exceptional capability of plasmonic structures to confine light into deep subwavelength volumes has fashioned rapid expansion of interest from both fundamental and applicative perspectives. Surface plasmon nanophotonics enables to investigate light-matter interaction in deep nanoscale and harness electromagnetic and quantum properties of materials, thus(More)
We present results on the spectroscopic study of the ionized gas in the high redshift radio galaxy USS0828+193 at z =2.57. Thanks to the high S/N of the emission lines in the Keck spectrum, we have been able to perform a detailed kinematic study by means of the spectral decomposition of the emission line profiles. This study reveals the existence of two(More)
We have searched for near-infrared extragalactic background light (EBL) in the data from the Near-InfraRed Spectrometer (NIRS) on the Infrared Telescope in Space (IRTS). After subtracting the contribution of faint stars and the zodiacal component based on modeling, a significant isotropic emission is obtained in the wavelength bands from 1.4 µm to 4.0 µm.(More)
Electrokinetic phenomena are a powerful tool used in various scientific and technological applications for the manipulation of aqueous solutions and the chemical entities within them. However, the use of DC-induced electrokinetics in miniaturized devices is highly limited. This is mainly due to unavoidable electrochemical reactions at the electrodes, which(More)
in the rest of the disk. The correlation remains notable even if we do not apply a thickness filter to the data or if we use another definition of the thickness (3, 11). The two maps are not independent, however; changing the density distribution in the arms will necessarily produce changes in the measured thickness unless the perturbations are distributed(More)
A wavefront sensing detector array is presented with capabilities suited towards high-order adaptive optics systems. The phase of the wavefront is sensed by modulating and synchronously sampling the fringes of a white light interferogram imaged onto the array. The nature of the modulation is characterized by a voltage signal, which is delivered as an input(More)
Surface plasmon polaritons (SPPs) are propagating excitations that arise from coupling of light with collective electron oscillations. Characterized by high field intensity and nanometric dimensions, SPPs fashion rapid expansion of interest from fundamental and applicative perspectives. However, high metallic losses at optical frequencies still make(More)
