Scattering asymmetry and second Kerker condition
Jorge Olmos-Trigo, Diego Romero Abujetas, Cristina Sanz Fernández +2
The nearly zero optical forward scattering and anti-dual conditions are usually associated to the so-called second Kerker condition, at which the electric and magnetic responses ar…
Surface plasmon polaritons on rough metal surfaces: Understanding the formation of laser induced periodic surface structures in metals
Y. Fuentes-Edfuf, J. A. Sanchez-Gil, C. Florian +3
The formation of self-organized laser induced periodic surface structures (LIPSS) in metals, semiconductors and dielectrics upon pulsed laser irradiation is a well-known phenomenon…
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…
From Fano resonances to bound states in the continuum in dipole arrays at THz frequencies
Diego R. Abujetas, Niels van Hoof, Stan ter Huurne +2
Fano resonances and bound states in the continuum (BICs) exhibit a rich phenomenology stemming from, respectively, their asymmetric line shapes and infinite quality factors. Here,…
Spin angular momentum in planar and cylindrical waveguides induced by transverse confinement and intrinsic helicity of guided light
D. R. Abujetas, J. A. Sánchez-Gil
In recent years, extraordinary spin angular momenta have been investigated in a variety of structured electromagnetic waves, being of especial interest in sub-wavelength evanescent…
Localized magnetic plasmons in all-dielectric mu<0 metastructures
R. Paniagua-Dominguez, L. S. Froufe-Perez, J. J. Saenz +1
Metamaterials are known to exhibit a variety of electromagnetic properties non-existing in nature. We show that an all-dielectric (non-magnetic) system consisting of deep subwavele…
