a Lines without symbols: Time trace of the pulsed THz field E(t) transmitted through the filled cavity on-resonance (red, xgap = 135 μm and x = 62.7 μm) and off-resonance (blue, xgap = 160 μm and x = 46 μm). Lines with dots: Relative change in the THz time profile \((-\Delta E(t)/E(t))\) for both configurations. b–d Zoom-in of the data around 0, 0.5, and 1.5 ps highlighted in panel (a), showing the relative signal enhancement for the resonant cavity
