Figure 8
NRR spectra in (a) the energy domain and (b) the time domain, calculated at the critical angle of the total reflection for the same sample parameters as in Figs. 5 and 7 by the exact matrix formalism and equations (6) and (7). The very small difference in the results confirms the validity of the generalized kinematic approximation, even in the region of total reflection, and the correctness of the depth selectivity interpretation for the used method. |
