Extended Data Fig. 2: THz characterization of the empty cavity.
From: Cavity-mediated thermal control of metal-to-insulator transition in 1T-TaS2

a. Time domain THz fields measured at the output of the empty cavity for three representative cavity frequencies \({\omega }_{c}\) indicated in legend. b. Cavity transmission spectra calculated from the fields shown in a. proving the tunability of the cavity fundamental mode.
