    • The plausibility of this result is well understood considering that for a sufficient length of the line, and for a short pulse duration (high (Formula presented), the impedance seen by the junction is essentially the same, that is, the characteristic impedance of the line (Formula presented)

    • One might suspect that the numerical analysis does indeed refer to a complete bounce trajectory, rather than to a half bounce. Under this assumption, the result obtained for (Formula presented) should be reduced to one half, that is, (Formula presented): a value that would make the discrepancy with Eq. (6) much more pronounced, even if still of the right order of magnitude

    • The definition of traversal time in tunneling is indeed a complicated question, and many different interpretations can be given [see, for example, E.H. Hauge and J.A. Støvneng, Rev. Mod. Phys. 61, 917 (1989)]. When we refer to the semiclassical traversal time, we mean the one derived in the Wentzel-Kramers-Brillouin nonperturbative semiclassical approximation, as given in Ref. 9. See also Refs. 1929.
