Abstract
A far infrared study for ceramic high-Tc superconductors, T12Ba2CaCu208 and YBa2Cu307, and for an oriented YBa2Cu307 thin film is reported. We present for the ceramics, that consist of strongly anisotropic crystallites, a new method of analysis that allows to extract properties of phonons and of charge carriers. We find that the dynamical conductivity of both the ceramics and the film in the normal state can be described by Drude's theory. The reflectivity of the film in the superconducting state corresponds to a Mattis-Bardeen like behavior with an energy gap 2Δ(0)/kTc = 4.2.
