The Kernel Method for Electrical Resistance Tomography
Antonello Tamburrino, Vincenzo Mottola
This paper treats the inverse problem of retrieving the electrical conductivity of a material starting from boundary measurements in the framework of Electrical Resistance Tomograp…
Adjoint-Based Gradient Evaluation for Metasurface Inverse Design via Affine Geometric Transformations
Vincenzo Mottola, Luisa Faella, Carlo Forestiere +1
The sharp increasing in fabrication capabilities of nanomaterials, and complex structures such as meta-surfaces and metalens, has opened to the possibility of employing them for ac…
QR-Recursive Compression of Volume Integral Equations for Electromagnetic Scattering by Large Metasurfaces
Vincenzo Mottola, Antonello Tamburrino, Luca Bergamaschi +5
In this paper, a novel QR decomposition-based compression scheme is combined with a volume integral equations method for the fast and efficient numerical computation of the scatter…
Tomography of nonlinear materials via the Monotonicity Principle
Vincenzo Mottola, Antonio Corbo Esposito, Gianpaolo Piscitelli +1
In this paper we present a first non-iterative imaging method for nonlinear materials, based on Monotonicity Principle. Specifically, we deal with the inverse obstacle problem, whe…
