Numerical characterization and engineering of transport in morphologically complex heterogeneous media

A multi-scale numerical methodology for the assessment of radiation and optical characteristics of complex structured soot-contaminated snow layers was investigated first. The methodology accounted for the exact morphology at the various scales and utilize ...

Optical characterization of multi-scale morphologically complex heterogeneous media – Application to snow with soot impurities

Sophia Haussener, Xiaoyu Dai

A multi-scale methodology for the radiative transfer analysis of heterogeneous media composed of morphologically-complex components on two distinct scales is presented. The methodology incorporates the exact morphology at the various scales and utilizes vo ...

An isogeometric boundary element method for electromagnetic scattering with compatible B-spline discretizations

Rafael Vazquez Hernandez

We outline the construction of compatible B-splines on 3D surfaces that satisfy the continuity requirements for electromagnetic scattering analysis with the boundary element method (method of moments). Our approach makes use of Non-Uniform Rational B-splin ...

Dipole codes attractively encode glue functions

Massimo Mastrangeli

Dipole words are sequences of magnetic dipoles, in which alike elements repel and opposite elements attract. Magnetic dipoles contrast with more general sets of bonding types, called glues, in which pairwise bonding strength is specified by a glue function ...

Physical bounds on absorption and scattering for cloaked sensors

Romain Christophe Rémy Fleury

We derive and discuss general physical bounds on the electromagnetic scattering and absorption of passive structures. Our theory, based on passivity and power conservation, quantifies the minimum and maximum allowed scattering for an object that absorbs a ...

Certified reduced basis method for electromagnetic scattering and radar cross section estimation

Jan Sickmann Hesthaven, Yvon Maday

We study nontrivial applications of the reduced basis method (RBM) for electromagnetic applications with an emphasis on scattering and the estimation of radar cross section (RCS). The method and several extensions are explained with two examples with diffe ...

A reduced basis method for electromagnetic scattering by multiple particles in three dimensions

Jan Sickmann Hesthaven, Bernhard Stamm

We consider the development of efficient and fast computational methods for parametrized electromagnetic scattering problems involving many scattering three dimensional bodies. The parametrization may describe the location, orientation, size, shape and num ...

Absolute absorption cross sections of ligand-free colloidal germanium nanocrystals

Extinction spectra of colloidal germanium nanocrystals suspended in benzonitrile without the use of ligands were measured, and absolute absorption cross sections are reported. Comparison to cross sections calculated using the Mie solution to Maxwell's equa ...

Ab initio engineering of Fano resonances

Olivier Martin, Benjamin Gallinet

In this work, we pave the route towards the engineering of strong and spectrally sharp Fano resonances in plasmonic nanostructures and derive analytical formulas for their line shape as a function of their electromagnetic response. Contrary to the original ...
