Frequency 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 ...
EPFL2023A Full-Wave Reference Simulator for Computing Surface Reflectance
Computing light reflection from rough surfaces is an important topic in computer graphics. Reflection models developed based on geometric optics fail to capture wave effects such as diffraction and interference, while existing models based on physical opti ...

Romain Christophe Rémy Fleury, Matthieu Francis Malléjac
Scattering wave systems that are periodically modulated in time offer many new degrees of freedom to control waves in both the spatial and frequency domains. Such systems, albeit linear, do not conserve frequency and require the adaptation of the usual the ...
2023Adaptive Symplectic Model Order Reduction Of Parametric Particle-Based Vlasov-Poisson Equation
Jan Sickmann Hesthaven, Nicolò Ripamonti, Cecilia Pagliantini
. High-resolution simulations of particle-based kinetic plasma models typically require a high number of particles and thus often become computationally intractable. This is exacerbated in multi-query simulations, where the problem depends on a set of para ...
AMER MATHEMATICAL SOC2023Linear scattering theory of short-pulse reflectometry
Stefano Coda, Stephan Brunner, Oleg Krutkin
The linear scattering theory of short pulse reflectometry is presented. An expression for the scattering signal is obtained by applying the perturbation theory approach for solving the Helmholtz equation. Based on these analytical results, a method for mea ...
2023Size dependence of second-harmonic scattering from nanoparticles: Disentangling surface and electrostatic contributions
Sylvie Roke, Arianna Marchioro, Bingxin Chu
Polarimetric angle-resolved second-harmonic scattering (AR-SHS) is an all-optical tool enabling the study of unlabeled interfaces of nano-sized particles in an aqueous solution. As the second harmonic signal is modulated by interference between nonlinear c ...

Luc Thévenaz, Tiago Filipe Pimentel Das Neves
Humidity is a critical environmental factor in various applications, and its temperature dependence must be considered when developing thermo-hygrometer fiber sensors. The optical fibers that constitute the sensor must have a temperature reference, which s ...
