Abstract.  Several types of multilayer metamaterial devices are studied to achieve cross-polarization conversion as well as subwavelength transmission enhancement. The surface current of three metamaterial layers reveals that the induced current around the apertures of the middle metal layer is the key to the physical mechanism. Furthermore, the simulated results show that the proposed devices have good performance on both the polarization conversion ratio and transmission rate. Lastly, a tunable cross-polarization conversion design is proposed and researched. These results can help to facilitate the development of high-sensitivity sensors and terahertz technology.
