We present a polarization converter composed of bi-layered metal films perforated with rectangle hole pairs in each film.The proposed converter can convert the polarization of an incident linearly-polarized electromagnetic wave to its orthogonal direction with high efficiency and large bandwidth in the infrared or microwave regions.To make sure of the mechanism of polarization conversion,the current and electric-field distributions at different resonant frequencies are analyzed.It is found that the cross-polarized transmission is due to the near-field coupling between hole pairs in neighboring metal films.Finally,a prototype of the proposed converter is fabricated and measured in the microwave region.Good agreement between the experimental and simulated results is obtained.
