Cloaked near-field probe for non-invasive near-field optical microscopy
Felipe Bernal Arango, Filippo Alpeggiani, Donato Conteduca +7
Near-field scanning optical microscopy is a powerful technique for imaging below the diffraction limit, which has been extensively used in bio-medical imaging and nanophotonics. Ho…
Spectral Causality and the Scattering of Waves
Zeki Hayran, Aobo Chen, Francesco Monticone
Causality - the principle stating that the output of a system cannot temporally precede the input - is a universal property of nature. Here, we show that analogous input-output rel…
Dielectric nonlocal metasurfaces for fully solid-state ultra-thin optical systems
Aobo Chen, Francesco Monticone
Most optical systems involve a combination of lenses separated by free-space regions where light acquires the required angle-dependent phase delay for a certain functionality. Very…
Physical limitations on broadband invisibility based on fast-light media
Mohamed Ismail Abdelrahman, Zeki Hayran, Aobo Chen +1
This note is a comment on a recent article [Tsakmakidis, et al., Nat Commun 10 (2019)] that presents a thought-provoking proposal to overcome the bandwidth restrictions of invisibi…
