Generalized nonlocal optical response in nanoplasmonics
N. Asger Mortensen, Søren Raza, Martijn Wubs +2
Metallic nanostructures exhibit a multitude of optical resonances associated with localized surface plasmon excitations. Recent observations of plasmonic phenomena at the sub-nanom…
Extremely confined gap surface plasmon modes excited by electrons
Søren Raza, Nicolas Stenger, Anders Pors +7
High spatial and energy resolution EELS can be employed for detailed characterization of both localized and propagating surface plasmon excitations supported by metal nanostructure…
Blueshift of the surface plasmon resonance in silver nanoparticles: substrate effects
Søren Raza, Wei Yan, Nicolas Stenger +2
We study the blueshift of the surface plasmon (SP) resonance energy of isolated Ag nanoparticles with decreasing particle diameter, which we recently measured using electron energy…
Nonlocal response in thin-film waveguides: loss versus nonlocality and breaking of complementarity
Søren Raza, Thomas Christensen, Martijn Wubs +2
We investigate the effects of nonlocal response on the surface-plasmon polariton guiding properties of the metal-insulator (MI), metal-insulator-metal (MIM), and insulator-metal-in…
