Disorder-induced signal filtering with topological metamaterials
Farzad Zangeneh-Nejad, Romain Fleury
Disorder, ubiquitously present in realistic structures, is generally thought to disturb the performance of analog wave devices, as it often causes strong multiple scattering effect…
Zero-index Weyl metamaterials
Farzad Zangeneh-Nejad, Romain Fleury
Depending on the geometry of their Fermi surfaces, Weyl semimetals and their analogues in classical systems have been classified into two types. In type I Weyl semimetals (WSMs), t…
Non-linear second-order topological insulators
Farzad Zangeneh-Nejad, Romain Fleury
We demonstrate, both theoretically and experimentally, the concept of non-linear second-order topological insulators, a class of bulk insulators with quantized Wannier centers and…
Topological Fano Resonances
Farzad Zangeneh Nejad, Romain Fleury
The Fano resonance is a widespread wave scattering phenomenon associated with a peculiar asymmetric and ultra-sharp line shape, which has found applications in a large variety of p…
Acoustic Birefringence via Non-Eulerian Metamaterials
Farzad Zangeneh-Nejad, Romain Fleury
The recently proposed concept of metamaterials has opened exciting venues to control wave-matter interaction in unprecedented ways. Here we demonstrate the relevance of metamateria…
Performing Mathematical Operations using High-Index Acoustic Metamaterials
Farzad Zangeneh-Nejad, Romain Fleury
The recent breakthrough in metamaterial-based optical computing devices [Science 343, 160 (2014)] has inspired a quest for similar systems in acoustics, performing mathematical ope…
Acoustic Analogues of High-Index Optical Waveguide Devices
Farzad Zangeneh-Nejad, Romain Fleury
High index optical waveguide devices such as slab waveguides, strip waveguides and fibers play extremely important roles in a wide range of modern applications including telecommun…
Spatial Integration by a Dielectric Slab Waveguide and its Planar Graphene-based Counterpart
Farzad Zangeneh-Nejad, Amin Khavasi
Motivated by the recent progress in analog computing [Science 343, 160 (2014)], a new approach to perform spatial integration is presented using a dielectric slab waveguide. Our ap…
Analog Optical Computing by Half-Wavelength Slabs
Farzad Zangeneh-Nejad, Amin Khavasi, Behzad Rejaei
A new approach to perform analog optical differentiation is presented using half-wavelength slabs. First, a half-wavelength dielectric slab is used to design a first order differen…
Analog computing by Brewster effect
Amir Youssefi, Farzad Zangeneh-Nejad, Sajjad AbdollahRamezani +1
Optical computing has emerged as a promising candidate for real-time and parallel continuous data processing. Motivated by recent progresses in metamaterial-based analog computing…
