High-Q transparency band in all-dielectric metasurfaces induced by a quasi bound state in the continuum
Diego R. Abujetas, Angela Barreda, Fernando Moreno +4
Bound states in the continuum (BICs) emerge throughout Physics as leaky/resonant modes that remain however highly localized. They have attracted much attention in Optics and Photon…
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…
Optical inspection of manufactured nanohole arrays to bridge the lab-industry gap
A. Franco, D. Otaduy, A. I. Barreda +4
Metallic nanohole arrays have shown their potential as sensing tools. Important research supported by sophisticated laboratory experiments have been recently carried out, that may…
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…
