Robust Fano-like Antiresonances in Large-Area Au-coated Ag-Nanoisland Ensembles
Valeria Nocerino, Francesca Di Carlo, Bruno Miranda +3
We report robust Fano-like spectral profiles in substrate-supported Au-coated Ag nanoislands fabricated by solid-state dewetting followed by Au overgrowth. Combining electrostatic…

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…
