  We revisit the classical problem of electromagnetic wave refraction from a
lossless dielectric to a lossy conductor, where both media are considered to be
non-magnetic, linear, isotropic and homogeneous. We derive the Fresnel
coefficients of the system and the Poynting vectors at the interface, in order
to compute the reflectance and transmittance of the system. We use a particular
parametrisation of the referred Fresnel coefficients so as to make a connection
with the ones obtained for refraction by an interface between two lossless
media. This analysis allows the discussion of an actual application, namely the
Fresnel polarisation of infra-red radiation by elemental bismuth, based on the
concept of pseudo Brewster's angle.
