Abstract

The effective far-infrared response of a superconductor-normal metal (S/N) composite is studied within the effective medium approximation. In particular, the effects of a finite relaxation time τ_s, which represents a generalization of the τ_s=0 Mattis-Bardeen form, are studied. The effects of varying τ_s and the concentration of the superconducting component on the effective conductivity and effective reflectivity of the composite are investigated. Possible applications of our calculations to the high temperature superconductors are discussed.
