Ultrawide thermal free-carrier tuning of dielectric antennas coupled to epsilon-near-zero substrates
The principal challenge for achieving reconfigurable optical antennas and metasurfaces is the need to generate continuous and large tunability of subwavelength, low-Q resonators. We demonstrate continuous and steady-state refractive index tuning at mid-infrared wavelengths using temperature-dependen...
