Analysis of magneto-optical Faraday effect in discontinuous magnetic medium with periodic air gaps

The magneto-optical Faraday effect in discontinuous magnetic media was analyzed by employing the matrix approach method. The discontinuous media have a one-dimensional array structure composed of magnetic materials (width D/sub M/) and air gaps (width D/sub G/) which are aligned alternately. The analysis reveals that, when the medium meets the condition of D/sub M/</spl lambda/<2(D/sub M/+D/sub G/), the Faraday spectrum varies considerably due to the discontinuous structure.
