(Color online) Transmission measurements taken along the hybrid metamaterial at 339.5 K. 0 mm indicates a position midway between the contacts. (Bottom inset) Measured transmission curves along with fits. (Top inset) Schematic of device indicating contact geometry and measurement locations.
(Color online) Extracted values for real (a) and imaginary (b) permittivity. Position of maximum permittivity indicated by dashed lines. (Inset) Schematic of SRR unit cell.
(Color online) (a) Spatial map of real permittivity varying with vertical position and frequency. Resonance frequency locations indicated by colored points. (b) Simulation of current flow through device. Color indicates power density (W/m3) and current flow is shown in the vector field (A/m2). Black rectangular outline indicates the location of the SRR array and VO2. Contact locations and shapes indicated by outlines at the bottom of the device.
