Abstract
Far-infrared optical properties of a thin film of NbN superconductor are reported in magnetic field up to 10 T. Transmission of monochromatic linearly polarized laser beam with frequency below and above an optical gap is measured both below and above Tc.
Transmission (B=0) is well described by the BCS-based model that approximates the sample as a mixture of superconductors with different Tc.
