摘要：
A new metamaterial polarization transformer is designed in our paper, which is a sandwich structure. There are three metal layers and two dielectric layers in it. The top and bottom layer is SRR structure, and the middle layer is a metal cross-shape structure. We give the simulated results of this model. It reaches a near-complete cross polarization conversion at 11.03 GHz, and the polarization conversion ratio is 96.6%. Then the internal physical mechanism is analyzed through the current and electric field distribution figures. The enantiomeric pattern and sandwich coupling structure help us to manipulate the electromagnetic wave polarizations. In addition, we load the lumped elements on the gaps of SRRs to control the polarization characteristic. And we find the impact of resistor is very big. Using this feature, we can manipulate the electromagnetic wave polarizations more flexibly.
