Design of a new kind of polarization splitter based on transformation optics

A scheme for a new two-dimensional polarization splitter is proposed based on the transformation optics. When a beam of arbitrary polarization illuminates upon the proposed polarization splitter, the TE (or TM) component is deflected whereas the TM (or TE) component propagates with no deflection. Moreover, the emerging propagation direction of the deflected component can be adjusted by rotating the polarization splitter. The simulation results demonstrated the feasibility and the flexibility of the polarization splitter. Design details and full-wave simulation results are provided.
