Most of the recently discovered superconductors, like all cuprates, MgB 2 , or Na x CoO 2 n H 2 O , are uniaxial crystals with metallic ab planes orthogonal to an insulating, or sometimes poorly conducting, c axis. The reflectivity R ab ( ω ) provides, through the optical conductivity σ ab ( ω ) , valuable information on the low-energy electrodynamics of these intriguing materials. However, in the far infrared, R ab ( ω ) 1 and a slight contamination from the c-axis response or an unsuitable choice of the extrapolation to ω = 0 may lead to large errors on σ ab ( ω ) . These issues are quantitatively discussed here with particular regard to La 2 x Sr x CuO 4 + y , one of the most-studied high- T c materials.
