    • Because of the limited thermal contact of the thin sample with the holder the lowest sample temperature in the transmission experiment was 10 K for x = 0.12 and as high as 24 K for x = 0.15. It was calibrated by a comparison of the Josephson plasma edge in the spectra of R and T.

    • Technically it is done by modeling ε(ω) with a large number of aoscillators (necessarty to reproduce experimental data), including the zero-frequency lossless mode of the SC condensate.

    • The samples are slightly wedged, which suppresses the Fabry-Pérot fringes. To account for this effect we introduced the rectangular thickness distribution with a width as an extra parameter. In this approximation the interference pattern was reproduced quite well, giving the thickness spreads of 0.5 μm for x = 0.12 and 1.5 μm for x = 0.15.

    • 1(x) ≠ 0 at very high energies, the latter is very small up to at least 1.8 eV.
