Spatiotemporal energy‐density distribution of time‐reversed electromagnetic fields
Marcos Rubinstein, Farhad Rachidi-Haeri, Hamidreza Karami, Elias Per Joachim Le Boudec, Nicolas Mora Parra
Time reversal exploits the invariance of electromagnetic wave propagation in reciprocal and lossless media to localize radiating sources. Time-reversed measurements are back-propagated in a simulated domain and converge to the unknown source location. The ...

Time reversal exploits the invariance of electromagnetic wave propagation in reciprocal and lossless media to localise radiating sources. Time-reversed measurements are back-propagated in a simulated domain and converge to the unknown source location. The ...
2023GaSLAM: An Algorithm for Simultaneous Gas Source Localization and Gas Distribution Mapping in 3D
Alcherio Martinoli, Chiara Ercolani, Lixuan Tang
Chemical gas dispersion poses considerable threat to humans, animals and the environment. The research areas of gas source localization and gas distribution mapping aim to localize the source of gas leaks and map the gas plume respectively, in order to hel ...
2022Particle Source Localization with a Low-Cost Robotic Sensor System: Algorithmic Design and Performance Evaluation
Alcherio Martinoli, Ali Marjovi, Xinxing Chen, Jian Huang
In this paper we tackle the problem of finding the source of particulate matter with a mobile robot equipped with a low-cost multi-channel optical particle counting sensor. The proposed method is based on the Infotaxis odor source localization algorithm an ...
2020Remote Source Coding Under Gaussian Noise: Dueling Roles of Power and Entropy Power
The distributed remote source coding (the so-called CEO) problem is studied in the case where the underlying source, not necessarily Gaussian, has finite differential entropy and the observation noise is Gaussian. The main result is a new lower bound for t ...
2019Pyramic: Full Stack Open Microphone Array Architecture And Dataset
René Beuchat, Robin Scheibler, Corentin Ferry
In this paper we introduce an open source and reproducible microphone array hardware design and an anechoic dataset recorded with this array. The Pyramic array has 48 microphones spread onto six identical modules connected to an FPGA-ARM combo. The arrange ...
IEEE2018Conceptual design of the beam source for the DEMO Neutral Beam Injectors
DEMO(DEMOnstration Fusion Power Plant) is a proposed nuclear fusion power plant that is intended to follow the ITER experimental reactor. The main goal ofDEMOwill be to demonstrate the possibility to produce electric energy from the fusion reaction. The in ...
Institute of Physics (IoP) and Deutsche Physikalische Gesellschaft2016Photogrammetric Mission Planner for RPAS
Jan Skaloud, Martin Rehak, Florian Gandor
This paper presents a development of an open-source flight planning tool for Remotely Piloted Aircraft Systems (RPAS) that is dedicated to high-precision photogrammetric mapping. This tool contains planning functions that are usually available in professio ...
2015HerMES: A DEFICIT IN THE SURFACE BRIGHTNESS OF THE COSMIC INFRARED BACKGROUND DUE TO GALAXY CLUSTER GRAVITATIONAL LENSING
Jean-Paul Richard Kneib, Huu Tuan Nguyen, Johan Richard
We have observed four massive galaxy clusters with the SPIRE instrument on the Herschel Space Observatory and measure a deficit of surface brightness within their central region after removing detected sources. We simulate the effects of instrumental sensi ...
Iop Publishing Ltd2013Multiple harmonic sound sources separation in the under-determined case based on both goniometric and beamforming approaches
Hervé Lissek, Xavier Falourd, Patrick Marmaroli
Usually acoustic beamformer or directive microphones are used in order to focus on known potential locations emitting sounds so as to identify and extract their major noise components. However performances of these techniques depend on the number of microp ...
