(a) Half-wave voltage-length product (\(V_{\pi } L_\pi\)) and the propagation losses as a function of electrode gap distance \(g\). The propagation loss is plotted considering \(V_\pi = 5\) V. The dashed rectangle points out the gap value providing a better trade-off between the \(V_{\pi } L_\pi\) and the propagation loss. (b) Energy in pico joules as a function of phase shift \(\alpha\). The energy is plotted at the trade-off gap value \(g =6.5~\mu\)m, requiring \(L_\pi =0.95\) cm at \(V_\pi =5\) V.
