Abstract
We propose a multi-channel filtering and polarization splitter based on periodic structure of the single-negative material and anisotropic material. With a small volume (only two periods), this structure has multi-transmission peaks with high Q value and perfect transmission. The s-polarization wave and p-polarization wave have different transmission spectra at normal incidence. The extinction ratios of the polarization splitter for s-polarization wave or p-polarization wave can overpass 1000 at normal incidence. The effect of incident direction on the transmittance and the extinction ratio are also discussed.
