Enhancing Electric Fields in High-Index Resonators by Flux Conservation of the Displacement Current Density
Bruno Miranda, Vincenzo D'Ambrosio, Giovanni Miano +2
Concentrating light within subwavelength spatial regions is a central topic in nanophotonics. In this letter, we introduce a general principle for the subwavelength localization an…
Resonance frequency and radiative Q-factor of plasmonic and dielectric modes of small objects
Carlo Forestiere, Giovanni Miano, Guglielmo Rubinacci
The electromagnetic scattering resonances of a non-magnetic object much smaller than the incident wavelength in vacuum can be either described by the electroquasistatic approximati…
Use of a spoof plasmon to optimize the coupling of infrared radiation to Josephson Junction fluxon oscillations
A. Tagliacozzo, S. De Nicola, D. Montemurro +6
We show that Infrared radiation impinging onto a 1-d array of grooves drilled in the superconductor electrode of a long overlap junction can improve matching between fluxon oscilla…
Quantum Theory of Radiative Decay Rate and Frequency Shift of Surface Plasmon Modes
Carlo Forestiere, Giovanni Miano, Mariano Pascale +1
In this paper we study, in the time domain, the interaction between localized surface plasmons and photons in arbitrarily shaped metal nanoparticles, by using the Hopfield approach…
Magnetoquasistatic Resonances of Small Dielectric Objects
Carlo Forestiere, Giovanni Miano, Mariano Pascale +4
A small dielectric object with positive permittivity may resonate when the free-space wavelength is large in comparison with the object dimensions if the permittivity is sufficient…
Full-wave electromagnetic modes and hybridization in nanoparticle dimers
Mariano Pascale, Giovanni Miano, Roberto Tricarico +1
The plasmon hybridization theory is based on a quasi-electrostatic approximation of the Maxwell's equations. It does not take into account magnetic interactions, retardation effect…
