Reconfigurable metasurface resonators with insulator-metal transitions

הרקע לפרויקט:

Tunable metasurfaces are the next frontier in flat optics and nanophotonics, with emerging applications such as LIDAR, AR, VR and many more. One of the few mechanisms that can meet the demanding requirements for tunable metasurface, is the insulator to metal phase transition in vanadium dioxide VO2, which occurs around 67 Celsius degrees. When undergoing this phase transition, the optical properties of VO2 changes abruptly and by a very large magnitude. In this project we use this material system to fabricate and characterize VO2 metasurfaces.

מטרת הפרויקט:

The purpose of the project is to study the optical properties and scattering response of tunable Mie resonator metasurfaces for both the far and near electromagnetic scattered fields. The metasurfaces will be implemented using vanadium dioxide (VO2) which undergoes an insulator-metal phase transition around 67C degrees. Using global and local heating, the tuning capabilities along with field patterns and linewidth a will be studied.

תכולת הפרויקט:

1. Design metasurfaces using electromagnetic numerical simulations.
2. Fabricate devices and
3. Test and characterize the devices.
