Scattering from Time-Modulated Transmission-Line Loads: Theory and Experiments in Acoustics
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 ...
2023Assessment of the transmission line theory in the modeling of multiconductor underground cable systems for transient analysis using a full-wave FDTD method
Farhad Rachidi-Haeri, Rafael Silva Alipio
In this paper, a rigorous and independent validation of two different approaches for calculating the ground-return impedance and admittance of multiconductor underground cable systems using the transmission line theory is carried out. Furthermore, analyses ...
2023Predicting nonlinear optical scattering with physics-driven neural networks
Demetri Psaltis, Carlo Gigli, Ahmed Ayoub
Deep neural networks trained on physical losses are emerging as promising surrogates for nonlinear numerical solvers. These tools can predict solutions to Maxwell's equations and compute gradients of output fields with respect to the material and geometric ...
AIP Publishing2023Calibration Transfer Methodology for Cloud Radars Based on Ice Cloud Observations
This article presents a calibration transfer methodology that can be used between radars of the same or dif-ferent frequency bands. This method enables the absolute calibration of a cloud radar by transferring it from another collocated instrument with kno ...
AMER METEOROLOGICAL SOC2023Multipolar expansions for scattering and optical force calculations beyond the long wavelength approximation
Olivier Martin, Karim Achouri, Andrei Kiselev, Marco Riccardi
We review three different approaches for the calculation of electromagnetic multipoles, namely, the Cartesian primitive multipoles, the Cartesian irreducible multipoles, and the spherical multipoles. We identify the latter as the best suited to describe th ...
AMER PHYSICAL SOC2022Multipolar Modeling of Spatially Dispersive Metasurfaces
Olivier Martin, Karim Achouri, Ville Tuovi Tiukuvaara
There is today a growing need to accurately model the angular scattering response of metasurfaces for optical analog processing applications. However, the current metasurface modeling techniques are not well suited for such a task since they are limited to ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Fundamental Properties and Classification of Polarization Converting Bianisotropic Metasurfaces
We provide a detailed discussion on the electromagnetic modeling and classification of polarization converting bianisotropic metasurfaces. To do so, we first present a general approach to compute the scattering response of suchmetasurfaces, which relies on ...

Christoph Bostedt, Daniela Rupp, Alessandro Colombo
We have recorded the diffraction patterns from individual xenon clusters irradiated with intense extreme ultraviolet pulses to investigate the influence of light-induced electronic changes on the scattering response. The clusters were irradiated with short ...
2020Angular 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 ...
2020On the Stability of FDTD-Based Numerical Codes to Evaluate Lightning-Induced Overvoltages in Overhead Transmission Lines
One of the main issues that has to be faced when evaluating lightning-induced overvoltages on a realistic network configuration is to implement the algorithm that solves the field-to-line coupling problem into an electromagnetic simulator that is able to r ...
