Abstract
We report for the first time absolute reflection measurements on YBaCu O HTSC thin film with c - axis oriented in the film plane. Measurement s have been fulfilled in a wide frequency range (20 - 5500 cm(-1)) for several film temperatures (13-300 K) with different polarizations of the incident light. The film revealed a strong anisotropy reflection. Some peculiarities are observed, though general behavior of the reflec tivity curves is in a fairly good agreement with previous results, obt ained on the perfect monocrystal samples. One can conclude, that a sim ple Drude model is hardly the best approach for the film data interpre tations.
