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…
Dynamical Regimes of Finite-Length Transmission Lines in Circuit Quantum Electrodynamics
Fabio Borrelli, Giovanni Miano, Adrian Parra-Rodriguez +1
We study the emergence of continuum, discrete-multimode, and single-mode regimes in finite-length transmission lines capacitively coupled to transmon qubits. We show that the appro…
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…
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…
