Abstract

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_M) and air gaps (width D_G) which are aligned alternately. The analysis reveals that, when the medium meets the condition of D_M<λ<2(D_M+D _G), the Faraday spectrum varies considerably due to the discontinuous structure
