Abstract

We theoretically and numerically studied the transmission of light through a subwavelength-perforated metal film, as well as through a homogeneous metal film with a Drude ac conductivity tensor, in the presence of a static magnetic field. Both the perforated and the homogeneous metal films are found to exhibit a magnetoinduced light transparency and a decreasing reflectivity due to cyclotron resonance. In particular, the cyclotron resonance and the surface plasmon resonance of the 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. The practical possibility of changing the sample transparency by application of a static magnetic field is discussed.
