Optothermal shaping of lamb waves with square and spiral phase fronts
Romain Christophe Rémy Fleury, Janez Rus, Aleksi Antoine Bossart
We introduce a Lamb-wave medium with tunable propagation velocities, which are controlled by a two-dimensional heating pattern produced by a laser beam. We utilized it to demonstrate that waves in an appropriately designed medium can propagate in the form ...
2024Generalised Kerr Microcomb Physics in Synchronously Driven Systems
In this thesis, the generation of microcombs under complex, non-trivial, and/or higher-order cavity conditions is explored, both in theory & simulation, and in practical experimentation. Pulse-driving of microresonators is investigated for the generation ...
EPFL2023Step detection in power system waveforms for improved RoCoF and frequency estimation
Mario Paolone, Asja Derviskadic, Guglielmo Frigo, Alexandra Cameron Karpilow
The evaluation of the signal frequency and Rate of Change of Frequency (RoCoF) from voltage or current waveforms is used for critical grid control, monitoring and protection applications. However, when step changes in the amplitude or phase of the signal o ...
