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…
Time-Domain Excitation of Finite-Lifetime Resonances and Their Exceptional Points
Asaf Farhi, Dror Hershkovitz, Andrea Alu +1
Resonances associated with complex-frequency poles are ubiquitous across physics and can arise in any open system, ranging from subwavelength particles and cavities to biological s…
Unveiling Topological Charges and Their Manipulation in Electronic Circuits
Zarko Sakotic, Predrag Stankovic, Vesna Bengin +3
Leveraging topological properties in the response of electromagnetic systems can greatly enhance their potential. Although the investigation of singularity-based electromagnetics a…
Saturable time-varying mirror based on an ENZ material
Romain Tirole, Emanuele Galiffi, Jakub Dranczewski +9
We report a switchable time-varying mirror, composed of an ITO-Au stack, which can be efficiently modulated in time with over a ten-fold increase in reflectivity, with a change of…
Low-Symmetry Nanophotonics
Alex Krasnok, Andrea Alú
Photonics and optoelectronics are at the foundations of widespread technologies, from high-speed Internet to systems for artificial intelligence, automotive LiDAR, and optical quan…
Topological scattering singularities and embedded eigenstates for polarization control and sensing applications
Zarko Sakotic, Alex Krasnok, Andrea Alú +1
Epsilon-near-zero and epsilon near-pole materials enable reflective systems supporting a class of symmetry-protected and accidental embedded eigenstates (EE) characterized by a div…
Coherent Control of Light Scattering
Alex Krasnok, Andrea Alú
Recently, a broad spectrum of exceptional scattering effects, including bound states in the continuum, exceptional points in PT-symmetrical non-Hermitian systems, and many others a…
Analytical Study of Sub-Wavelength Imaging by Uniaxial Epsilon-Near-Zero Metamaterial Slabs
Giuseppe Castaldi, Silvio Savoia, Vincenzo Galdi +2
We discuss the imaging properties of uniaxial epsilon-near-zero metamaterial slabs with possibly tilted optical axis, analyzing their sub-wavelength focusing properties as a functi…
