Refractive-index change in the BTO material according to equation (6) as a function of frequency for varying ratios R w with C = 4. The measured permittivity of BTO in this work (Table 1) was used as the input for BTO and is plotted in green. n is normalized to its low-frequency value at 100 MHz to highlight the frequency dependence for each case.
