Observation of non-reciprocal harmonic conversion in real sounds
Romain Christophe Rémy Fleury, Hervé Lissek, Xinxin Guo
Reciprocity guarantees that in most media, sound transmission is symmetric between two points of space when the location of the source and receiver are interchanged. This fundamental law can be broken in non-linear media, often at the cost of detrimental i ...
2023Harmonic decomposition of the trace of 1D transfer matrices in layered media
The Transfer Matrix formalism is ubiquitous when it comes to study wave propagation in various stratified media, applications ranging from Seismology to Quantum Mechanics. A relation between variables at two points in two different layers can be establishe ...
2022Modelling of AC/DC Interactions of Converter-Interfaced Resources for Harmonic Power-Flow Studies in Microgrids
Mario Paolone, Yihui Zuo, Andreas Martin Kettner, Johanna Kristin Maria Becker
Modern power distribution systems experience a large-scale integration of Converter-Interfaced Distributed Energy Resources (CIDERs). As acknowledged by recent literature, the interaction of individual CIDER components and different CIDERs through the grid ...
2022Weak nonlinearity for strong non-normality
François Gallaire, Edouard Boujo, Yves-Marie François Ducimetière
We propose a theoretical approach to derive amplitude equations governing the weakly nonlinear evolution of non-normal dynamical systems, when they experience transient growth or respond to harmonic forcing. This approach reconciles the non-modal nature of ...
2022Optically reconfigurable quasi-phase-matching in silicon nitride microresonators
Camille Sophie Brès, Jianqi Hu, Anton Stroganov, Edgars Nitiss
Quasi-phase-matching has long been a widely used approach in nonlinear photonics, enabling efficient parametric frequency conversions such as second-harmonic generation. However, in silicon photonics the task remains challenging, as materials best suited f ...
