The far-infrared absorption spectrum of a granular superconductor consisting of Sn spheres in a KCl host is calculated using the longitudinal dielectric function in a nonlocal theory for the polarizability of a small sphere. The theory can explain the frequency dependence, but not the anomalously large magnitude of the observed absorption.
