Optical forces, helicity, angular momentum and how they are all intertwined
Iker Gómez-Viloria, Enrique Ayllón García, Jorge Olmos-Trigo +4
The theoretical description of optical forces and torques on micron_sized particles is a crucial area of research and has formed the foundation for advancements in optical trapping…
Characterizing the Backscattered Spectrum of Mie Spheres
Martín Molezuelas-Ferreras, Álvaro Nodar, María Barra-Burillo +10
This study describes both experimentally and theoretically an important hitherto undiscovered feature of the scattering of micron_sized spherical objects when illuminated with high…
Lorentz invariant materials and metamaterials
Jon Lasa-Alonso, Gabriel Molina-Terriza
We show that electromagnetic constitutive relations of materials, defined by a scalar permittivity, , and permeability, , are the same for all inertial observers pr…
On the origin of the Kerker phenomena
Jon Lasa-Alonso, Chiara Devescovi, Carlos Maciel-Escudero +2
We provide an insight into the origin of the phenomena reported 40 years ago by Kerker, Wang and Giles (Journal of the Optical Society of America, 73, 6, pp. 765-767, (1983)). We s…
Characterizing cylindrical particles upon local measurements of two Stokes parameters
Jon Lasa-Alonso, Iker Gómez-Viloria, Álvaro Nodar +3
Researchers routinely characterize optical samples by computing the scattering cross-section. However, the experimental determination of this magnitude requires the measurement and…
Resonant helicity mixing of electromagnetic waves propagating through matter
Jon Lasa-Alonso, Jorge Olmos-Trigo, Chiara Devescovi +3
Dual scatterers preserve the helicity of an incident field, whereas antidual scatterers flip it completely. In this setting of linear electromagnetic scattering theory, we provide…
Capturing near-field circular dichroism enhancements from far-field measurements
Jorge Olmos-Trigo, Jon Lasa-Alonso, Iker Gómez-Viloria +2
Molecular Circular dichroism (CD) spectroscopy faces significant limitations due to the inherent weakness of chiroptical light-matter interactions. In this view, resonant optical a…
Correlations between helicity and optical losses within general electromagnetic scattering theory
Jon Lasa-Alonso, Jorge Olmos-Trigo, Aitzol García-Etxarri +1
Helicity preserving nanostructures and metasurfaces have been recently proposed as suitable candidates to enhance spectroscopic features of chiral matter. With this in mind, we hig…
Multiple Kerker anapoles in dielectric microspheres
Cristina Sanz-Fernández, Martín Molezuelas, Jon Lasa-Alonso +3
High refractive index dielectric spheres present remarkable light-scattering properties in the spectral range dominated by dipolar modes. However, most of these properties are abse…
Kerker Conditions Upon Lossless, Absorption, and Optical Gain Regimes
Jorge Olmos-Trigo, Cristina Sanz-Fernández, Diego R. Abujetas +6
The directionality and polarization of light show peculiar properties when the scattering by a dielectric sphere can be described exclusively by electric and magnetic dipolar modes…
Surface-Enhanced Circular Dichroism spectroscopy on periodic dual nanostructures
Jon Lasa-Alonso, Diego R. Abujetas, Alvaro Nodar +5
Increasing the sensitivity of chiral spectroscopic techniques such as circular dichroism (CD) spectroscopy is a current aspiration in the research field of nanophotonics. Enhancing…
