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…

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…
