An interior penalty coupling strategy for isogeometric non-conformal Kirchhoff-Love shell patches
Annalisa Buffa, Pablo Antolin Sanchez, Giuliano Guarino
This work focuses on the coupling of trimmed shell patches using Isogeometric Analysis, based on higher continuity splines that seamlessly meet the C 1 \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackag ...
Springer2024Frequency and time domains interactions in nanophotonics
In this thesis, we discuss the problems of scattering and optical manipulation related to nanosystems of different complexities. The multipolar decomposition method is used to represent scattering processes in nanosystems as a series of elementary excitati ...
EPFL2023Angular Scattering Properties of Metasurfaces
This article aims at studying the angular scattering properties of bianisotropic metasurfaces and clarifying the different roles played by tangential and normal polarization densities. Different types of metasurfaces are considered for this study and are c ...
2020Language model domain adaptation for automatic speech recognition
This report provides an overview of the work carried out in improving Language Model (LM) development used during the decoding of an Automatic Speech Recognition (ASR) system. The goal of this work is to develop a robust language model that can be adapted ...
Idiap2020System and method for projecting images through scattering media
Demetri Psaltis, Christophe Moser, Babak Rahmani
The invention discloses a system (1) and method to guide light through a scattering medium (4) and project images on a screen (5) placed after the medium (4). Many of the shortcomings of previous approaches for guiding light through scattering medium (4) h ...
2020Symmetries and Angular Scattering Properties of Metasurfaces
We study the angular scattering behavior of bianisotropic metasurfaces and deduce relationships between the corresponding symmetrical angular scattering properties and the structural symmetries of their scattering particles. This may be of practical intere ...
IEEE2019Imaging complex objects using learning tomography
Michaël Unser, Demetri Psaltis, Alexandre Goy, Joowon Lim
Optical diffraction tomography (ODT) can be described using the scattering process through an inhomogeneous media. An inherent nonlinearity exists relating the scattering medium and the scattered field due to multiple scattering. Multiple scattering is oft ...
SPIE-INT SOC OPTICAL ENGINEERING2018An isogeometric boundary element method for electromagnetic scattering with compatible B-spline discretizations
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 ...

We outline the construction of compatible B-splines on 3D surfaces that satisfy the continuity requirements for electromagnetic scatter- ing analysis with the boundary element method (method of moments). Our approach makes use of Non-Uniform Rational B-spl ...
MATHICSE2017Physical bounds on absorption and scattering for cloaked sensors
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 ...
