Abstract :
Here we report on the integration of metallic nanorods with the phase-change material Vanadium Dioxide (VO2). The change in its optical constants that accompanies the VO2 phase transition permits the modulation of the resonant frequencies of these dipoles. This technique will underpin the development of dynamically tunable optical antennas.
