| Abstract: | The influence of a quasicrystalline Al-Pd-Re film on the shift and broadening of surface polaritons of a substrate (sapphire)
has been studied. Measurements have been performed both on a sample containing only the quasicrystalline phase and on a sample
which, in addition to the quasicrystalline phase, contains the crystalline (metallic) phase. The complex dielectric function
of the films in the mid-IR region (650–800 cm−1) has been estimated. |
