Flow stabilization with active hydrodynamic cloaks
Yaroslav A. Urzhumov, David R. Smith
We demonstrate that fluid flow cloaking solutions based on active hydrodynamic metamaterials exist for two-dimensional flows past a cylinder in a wide range of Reynolds numbers, up…
Low-loss directional cloaks without superluminal velocity or magnetic response
Yaroslav Urzhumov, David R. Smith
The possibility of making an optically large (many wavelengths in diameter) object appear invisible has been a subject of many recent studies. Exact invisibility scenarios for larg…
Electronically reconfigurable metal-on-silicon metamaterial
Yaroslav Urzhumov, Jae Seung Lee, Talmage Tyler +5
Reconfigurable metamaterial-based apertures can play a unique role in both imaging and in beam-forming applications, where current technology relies mostly on the fabrication and i…
Magnetic superlens-enhanced inductive coupling for wireless power transfer
Da Huang, Yaroslav Urzhumov, David R. Smith +2
We investigate numerically the use of a negative-permeability "perfect lens" for enhancing wireless power transfer between two current carrying coils. The negative permeability sla…
Isotropic-medium three-dimensional cloaks for acoustic and electromagnetic waves
Yaroslav Urzhumov, Nathan Landy, David R. Smith
We propose a generalization of the two-dimensional eikonal-limit cloak derived from a conformal transformation to three dimensions. The proposed cloak is a spherical shell composed…
