Gold nanodoughnut as an outstanding nanoheater for photothermal applications
Javier González-Colsa, Guillermo Serrera, José María Saiz +5
Photoinduced hyperthermia is a cancer therapy technique that induces death to cancerous cells via heat generated by plasmonic nanoparticles. While previous studies have shown that…
VO2 Nanocrystals for Designer Phase-Change Metamaterials
Jimmy John, Yael Gutierrez, Zhen Zhang +5
Subwavelength nanoparticles can support electromagnetic resonances with distinct features depending on their size, shape and nature. For example, electric and magnetic Mie resonanc…
Brewster quasi bound states in the continuum in all-dielectric metasurfaces from single magnetic-dipole resonance meta-atoms
Diego R. Abujetas, Angela Barreda, Fernando Moreno +4
Bound states in the continuum (BICs) are ubiquitous in many areas of physics, attracting especial interest for their ability to confine waves with infinite lifetimes. Metasurfaces…
Evaluation of effective medium theories for spherical nano-shells
Yael Gutierrez, Dolores Ortiz, Rodrigo Alcaraz de la Osa +4
Current effective medium theories for nano-shells are reviewed. A new method for calculating the effective dielectric function of a core-shell nanoparticle is presented and compare…
Electromagnetic polarization controlled perfect switching effect with high refractive index dimers. the beam-splitter configuration
Angela I. Barreda, Hassan Saleh, Amelie Litman +3
High Refractive Index (HRI) dielectric particles smaller than the wavelength, isolated or forming a designed ensemble are ideal candidates as new multifunctional elements for build…
Directional Fano Resonances at Light Scattering by a High Refractive Index Dielectric Sphere
Michael I. Tribelsky, Jean-Michel Geffrin, Amelie Litman +2
In this research, we report the experimental evidence of the directional Fano resonances at the scattering of a plane, linearly polarized electromagnetic wave by a homogeneous diel…
Spectral behavior of localized plasmon resonances in the near- and far-field regimes. Comment on The spectral shift between near- and far-field resonances of optical nano-antennas
Fernando Moreno, Pablo Albella, Manuel Nieto-Vesperinas
In a recent paper by Menzel et al. (Opt. Exp. 22, 9971 (2014)), its authors analyze the spectral red-shift effect of plasmonic resonances of metallic nano-antennas between the far-…
Electric and magnetic dipolar response of Germanium spheres: Interference effects, scattering anisotropy and optical forces
Raquel Gómez-Medina, Braulio García-Cámara, Irene Suárez-Lacalle +4
We address the scattering cross sections, and their consequences, for submicrometer Germanium spheres. It is shown that there is a wide window in the near infrared where light scat…
