The authors present far-infrared measurements on YBCO films deposited on an Si substrate. In particular, they measured the radiation intensity transmitted in the spectral range 50-550 cm-1 through two samples composed of YBCO films of different thickness deposited on the same Si substrate. With this procedure, they derived the extinction coefficient of YBCO at temperatures above and below the critical temperature Tc. Above Tc the data can be described by the Drude model. Below Tc the data are consistent with the results of the Mattis-Bardeen theory for the superconducting phase, assuming an energy gap of about 250 cm-1.
