Abstrakt: We have studied the far infrared reflectance of the mixed phase superconductor Y1.2Ba0.8CuO4-y. The reflectance spectrum shows sharp phonon resonances and an electronic contribution that we attribute to reflection at a mesh-like structure of the conducting phase embedded in nonconducting material; in comparison, the reflectance of single phase superconducting material is mainly determined by the dynamical electronic conductivity.
