Abstract
The far-infrared transmission spectra for high-conductivity Bi2Sr2CaCu2O8 films with the radiation polarized in the ab plane have been measured for temperatures above and below Tc. The normal-state properties show a Drude-like response. The transmission spectrum can be used to derive both the dc conductivity (90 1/4 cm at Tc) and the relaxation rate (165 cm-1 at Tc). If an energy gap at 3.5kTc or higher is assumed then the film is in the clean limit. In the superconducting state the transmission drops at low frequency but remains finite.
