Switchable Vanadium Dioxide Kerker Metasurface
OSA Advanced Photonics Congress (AP) 2019 (IPR, Networks, NOMA, SPPCom, PVLED), 2019We developed a switchable filter by incorporating vanadium dioxide (VO2) into a metasurface that obeys the Kerker condition. By varying the temperature of the VO2, the filter switches between broadly transparent and notch filter states.

Thermal filaments in vanadium dioxide
IEEE Transactions on Electron Devices, 1969A relatively simple thin-film structure using vanadium dioxide is analyzed in detail to show that high-temperature, low-resistivity filaments can exist in VO 2 under appropriate electrical bias. These filaments will dominate both the static and dynamic electrical behavior of the structure, giving rise to V-I characteristics similar to those expected ...

Vanadium dioxide phase change switches
SPIE Proceedings, 2015The thermally driven metal insulator transition in vanadium dioxide (VO2) is used to create a low loss millimeter wave switch which operates up to and beyond W-band frequencies. We have built RF switches using vanadium dioxide thin films fabricated within a section of inverted transmission line with integrated on chip heaters to provide local thermal ...

Surface and bulk conductivity of vanadium dioxide
Technical Physics, 2017The dc and ac resistances of a TR-68 thermistor based on the vanadium dioxide film have been measured and the temperature dependence of the resistance in the semiconductor–metal transition region under adsorption has been studied. The energy band model has been proposed, which explains the anomalous response to adsorption of donor gases by the ...
