Comment on "Angle insensitive filters based on Fabry-Perot resonance structures" [J. Appl. Phys. 136, 193102 (2024)]
Michele Cotrufo
In a recent paper, Cao et al. investigated numerically a structure made of two cascaded metasurfaces to realize angle-independent filters. Their calculations show a remarkable perf…

Nonlocal Metasurface Lens for Long-Wavelength Infrared Radiation
Federico De Luca, Sriram Guddala, Michele Cotrufo +3
Dielectric metasurfaces are structured thin films with thickness smaller than the wavelength that aim at replacing and enhancing conventional bulk optical components by structuring…
