A Compressive Sensing Framework for EMI Source Localization Using a Metalens Structure: Localization Beyond the Diffraction Limit

Farhad Rachidi-Haeri, Marcos Rubinstein, Mohammad Azadifar, Hamidreza Karami

In this article, we propose a novel approach for the localization of electromagnetic interference (EMI) sources based on the concept of compressive sensing and metalenses. We show that using the spatial and frequency dispersion offered by the metalens, we ...

Coordinated Path Planning for Surface Acoustic Beacons for Supporting Underwater Localization

Alcherio Martinoli, Anwar Ahmad Quraishi

Accurate localization is one of the biggest challenges in underwater robotics. The primary reasons behind that are unavailability of satellite-based positioning below the surface, and lack of clear features in natural water bodies for visually aided locali ...

Downside Up:Rethinking Parcel Position for Aerial Delivery

Dario Floreano, Przemyslaw Mariusz Kornatowski, William John Stewart

The conventional approach to parcel placement in most delivery drone designs today is to place the parcel centrally beneath the drone's rotor plane. However, if the parcel is too large, this will result in an obstruction of the propeller slipstream, incurr ...
