Bode-Fano Limits to Broadband Absorption by Small Particles
Emanuele Corsaro, Andrea Alù, Carlo Forestiere
Nanostructures can be designed to absorb light efficiently at resonance despite their subwavelength footprint, but causality and passivity fundamentally limit the bandwidth over wh…
Exceptional Points in the Scattering Resonances of a Sphere Dimer
Emanuele Corsaro, Filippo Capolino, Carlo Forestiere
We investigate exceptional points of degeneracy (EPDs) in electromagnetic scattering of a sphere dimer from the electroquasistatic limit to the fully retarded regime. In the quasis…
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…
Multilevel Fast Multipole Algorithm for Electromagnetic Scattering by Large Metasurfaces using Static Mode Representation
Emanuele Corsaro, Giovanni Miano, Antonello Tamburrino +2
Metasurfaces, consisting of large arrays of interacting subwavelength scatterers, pose significant challenges for general-purpose computational methods due to their large electric…
