Current oscillations in Vanadium Dioxide: evidence for electrically triggered percolation avalanches
Tom Driscoll, Jack Quinn, Giwan Seo +5
In this work, we experimentally and theoretically explore voltage controlled oscillations occurring in micro-beams of vanadium dioxide. These oscillations are a result of the rever…

Reconfigurable Gradient Index using VO2 Memory Metamaterials
M. D. Goldflam, T. Driscoll, B. Chapler +9
We demonstrate tuning of a metamaterial device that incorporates a form of spatial gradient control. Electrical tuning of the metamaterial is achieved through a vanadium dioxide la…

Memory Metamaterials
Tom Driscoll, Hyun-Tak Kim, Byung-Gyu Chae +7
The resonant elements that grant metamaterials their unique properties have the fundamental limitation of restricting their useable frequency bandwidth. The development of frequenc…
