| Abstract: | The diffraction characteristics of subwavelength metallic and dielectric gratings are discussed by means of rigorous coupled-wave analysis(RCWA).A double-layer subwavelength metal-dielectric grating used as polarizer is presented.At the same time,reflectivity properties for the TM polarization and the reflection polarization ratio of the polarizer are attained with RCWA. |
