An experimental researcher whose work with <M. Tinkham> measured how thin superconducting films transmit radiation of different frequencies. Extracting their complex <electrical conductivity> revealed the onset of absorption above an energy threshold. That threshold supplied evidence for a <superconducting energy gap>, connecting optical response with the spectrum of allowed electronic excitations.<Conductivity of Superconducting Films for Photon Energies between 0.3 and 40kTc by R. E. Glover III and M. Tinkham>[Abstract: lead and tin film transmission, complex conductivity and excitation gap]{ref}
