Nature-inspired three-dimensional surface serration topologies enable silent flight by suppressing airfoil-turbulence interaction noise
Zixiao Wei, Stanley Wang, Sean Farris +6
As natural predators, owls fly with astonishing stealth due to the sophisticated serrated surface morphology of their feathers that produces advantageous flow characteristics and f…
Generalized effective dynamic constitutive relation for heterogeneous media: Beyond the quasi-infinite and periodic limits
Jeong-Ho Lee, Zhizhou Zhang, Grace X. Gu
Dynamic homogenization theories are powerful tools for describing and understanding the behavior of heterogeneous media such as composites and metamaterials. However, a major chall…
Maximum Electro-Momentum Coupling in Piezoelectric Metamaterial Scatterers
Jeong-Ho Lee, Zhizhou Zhang, Grace X. Gu
Analogous to electromagnetic bianisotropy, engineered piezoelectric metamaterials can possess electro-momentum coupling between the macroscopic momentum and electric stimuli. This…
Rational design of piezoelectric metamaterials with tailored electro-momentum coupling
Zhizhou Zhang, Jeong-Ho Lee, Grace X. Gu
Piezoelectric materials have wide sensing and energy transduction applications due to their inherent coupling of mechanical deformation and electric field. Recent discoveries have…
Learning hidden elasticity with deep neural networks
Chun-Teh Chen, Grace X. Gu
We introduce a de novo elastography method to learn the elasticity of solids from measured strains. The deep neural network in our new method is supervised by the theory of elastic…
