Title: "Reconfigurable Microwave Devices using Insulator-Metal Phase Transition in Vanadium Dioxide"

Date: Friday, 24th April 2026 - Time: 4 PM

Hi Tea & Coffee: 5 PM

Venue: CeNSE Seminar Hall

Abstract:

Vanadium dioxide (VO2) is a phase-transition material which exhibits a reversible structural and 
an associated insulator-metal phase transition at 68 ºC. This phase transition is accompanied by 
a large change in VO2 resistivity and dielectric-response properties, enabling a host of 
electromagnetic switching applications from microwave to THz, Infra-red, and visible wavelengths. 
In this talk, several reconfigurable microwave devices realised using VO2 will be presented along 
with detailed modelling of the experimentally observed characteristics.
