We have conducted a theoretical and calculational study of the transmission of light through a sub-wavelength-perforated metal film, as well as through a homogeneous metal film, with Drude ac conductivity tensor in the presence of a static magnetic field. Both perforated and homogeneous metal films are found to exhibit a magneto-induced light transparency and a decreasing of reflectivity due to cyclotron resonance. In particular, the cyclotron resonance and the surface plasmon resonance of a perforated metal film move to higher frequencies with increasing magnetic field, bringing about large changes in the extraordinary light transmission peaks predicted to occur in such a film. In the case of periodic microstructures, these phenomena depend not only on the magnitude of the applied in-plane magnetic field, but also on its direction. This is due to the nonlinear dependence of the local electromagnetic response on that field. The practical possibility of changing the sample transparency by application of a static magnetic field (e.g., a new type of magneto-optical switch) is discussed.
