Polarization Imaging and Edge Detection with Image-Processing Metasurfaces
Michele Cotrufo, Sahitya Singh, Akshaj Arora +2
Optical metasurfaces have been recently explored as ultrathin analog image differentiators. By tailoring the momentum transfer function, they can perform efficient Fourier-filterin…
Spatio-Temporal Coupled Mode Theory for Nonlocal Metasurfaces
Adam Overvig, Sander A. Mann, Andrea Alù
Diffractive nonlocal metasurfaces have recently opened a broad range of exciting developments in nanophotonics research and applications, leveraging spatially extended (yet locally…
Ghost line waves
Massimo Moccia, Giuseppe Castaldi, Andrea Alù +1
Time-harmonic electromagnetic plane waves in anisotropic media can exhibit complex-valued wavevectors (with nonzero real and imaginary parts) even in the absence of material dissip…
Twist-Induced Hyperbolic Shear Metasurfaces
Simon Yves, Emanuele Galiffi, Xiang Ni +2
Following the discovery of moiré-driven superconductivity in twisted graphene multilayers, twistronics has spurred a surge of interest in tailored broken symmetries through angular…
An Asymmetric Spoof-Fluid-Spoof Acoustic Waveguide and its Application as a CO Sensor
Nathan Perchikov, Đorđe Vujić, Branimir Bajac +3
We study pressure acoustic propagation in asymmetric spoof-fluid-spoof acoustic waveguides and its potential application in acoustic gas sensors. First, a stable and efficient anal…
Tunable Magnetless Optical Isolation with Twisted Weyl Semimetals
Vladislav Chistyakov, Viktar S. Asadchy, Shanhui Fan +2
Weyl semimetals hold great promise in revolutionizing nonreciprocal optical components due to their unique topological properties. By exhibiting nonreciprocal magneto-optical effec…
