Propagation length and as a function of frequency.
a) Propagation length as a function of frequency for the full range of frequencies, as well as focused on the low frequency region (inset); b) A portion of the dispersion displayed in Fig 6, focused on the experimentally relevant region. Several points (i-iv) are shown on both plots for comparison.
