GAN-driven Electromagnetic Imaging of 2-D Dielectric Scatterers
Ehtasham Naseer, Ali Imran Sandhu, Muhammad Adnan Siddique +3
Inverse scattering problems are inherently challenging, given the fact they are ill-posed and nonlinear. This paper presents a powerful deep learning-based approach that relies on…
Observation of ultra-high-Q resonators in the ultrasound via bound states in the continuum
Mohamed Farhat, Younes Achaoui, Julio A. Iglesias Martinez +3
The confinement of waves in open systems represents a fundamental phenomenon extensively explored across various branches of wave physics. Recently, significant attention has been…
Sound Waveguiding by Spinning: An Avenue towards Unidirectional Acoustic Spinning Fibers
Mohamed Farhat, Pai-Yen Chen, Ying Wu
Waveguiding in general and acoustic waveguiding in particular are possible at the condition of having a transverse "discontinuity" or modulation of the refractive index. We propose…
A Generative deep learning approach for shape recognition of arbitrary objects from phaseless acoustic scattering data
W. W. Ahmed, M. Farhat, P. -Y. Chen +2
We propose and demonstrate a generative deep learning approach for the shape recognition of an arbitrary object from its acoustic scattering properties. The strategy exploits deep…
Machine learning for knowledge acquisition and accelerated inverse-design for non-Hermitian systems
W. W. Ahmed, M. Farhat, K. Staliunas +2
Non-Hermitian systems offer new platforms for unusual physical properties that can be flexibly manipulated by redistribution of the real and imaginary parts of refractive indices,…
Scattering Cancellation based Cloaking for the Maxwell-Cattaneo Heat Waves
M. Farhat, S. Guenneau, P. -Y. Chen +2
In this work we theoretically propose scattering cancellation-based cloaks for heat waves that obey the Maxwell-Cattaneo equation. The proposed cloaks possess carefully tailored di…
Cloaking and anamorphism for light and mass diffusion
Sebastien Guenneau, Andre Diatta, Tania M. Puvirajesinghe +1
We first review classical results on cloaking and mirage effects for electromagnetic waves. We then show that transformation optics allows the masking of objects or produces mirage…
Flexural Mie Resonances: Localized Surface Platonic Modes
M. Farhat, S. Guenneau, P. Y. Chen +2
Surface plasmons polaritons were thought to exist only in metals near their plasma frequencies. The concept of spoof plasmons extended the realms of plasmonics to domains such as r…
Theory of diffusive light scattering cancellation cloaking
Mohamed Farhat, Pai-Yen Chen, Sebastien Guenneau +3
We report on a new concept of cloaking objects in diffusive light regime using the paradigm of the scattering cancellation and mantle cloaking techniques. We show numerically that…
Biharmonic Split Ring Resonator Metamaterial: Artificially dispersive effective density in thin periodically perforated plates
M. Farhat, S. Enoch, S. Guenneau
We present in this paper a theoretical and numerical analysis of bending waves localized on the boundary of a platonic crystal whose building blocks are split ring resonators (SRR)…
Reply to the Comment on "A self-assembled three-dimensional cloak in the visible" in Scientific Reports 3, 2328
S. Mühlig, A. Cunningham, J. Dintinger +6
In a recent comment arxiv:1310.1503 Miller et al. noted that a cloak we previously presented (Scientific Reports 3, 2328) that exploits a scattering cancellation technique to rende…
A perfect absorber made of a graphene micro-ribbon metamaterial
Rasoul Alaee, Mohamed Farhat, Carsten Rockstuhl +1
Metamaterial-based perfect absorbers promise many applica- tions. Perfect absorption is characterized by the complete suppression of transmission and reflection and complete dissip…
Cloaking dielectric spherical objects by a shell of metallic nanoparticles
Stefan Muhlig, Mohamed Farhat, Carsten Rockstuhl +1
We show that dielectric spheres can be cloaked by a shell of amorphously arranged metallic nanoparticles. The shell represents an artificial medium with tunable effective propertie…
Finite elements modelling of scattering problems for flexural waves in thin plates: Application to elliptic invisibility cloaks, rotators and the mirage effect
Mohamed Farhat, Sebastien Guenneau, Stefan Enoch
We propose a finite elements algorithm to solve a fourth order partial differential equation governing the propagation of time-harmonic bending waves in thin elastic plates. Specia…
