Extinction, elastic-scattering, and absorption cross-sections for selected nanoparticle morphologies.
Contact F. J. García de Abajo for details.
We calculate cross sections using the analytical methods described in
R. Yu, L. M. Liz-Marzán, and F. J. García de Abajo, Chem. Soc. Rev. (2017)
for nanoparticles with the selected morphologies and user-specified
size length L, aspect ratio R, and dielectric function ε(ω).
These calculations are accurate within the ranges
L<200 nm and 1<R<8.†
The size length and aspect ratio are defined for each type of particle in
the schemes below. The incident light polarization is along the direction
of the segment labeled L in the schemes of the particles.
†Note that for some geometries, R must be above certain threshold values (e.g., >1 for rings and >2 for cages).
