In this paper, a bi-layered ultra-thin multifunctional chiral metasurface is proposed to obtain asymmetric transmission (AT), cross-polarization conversion (CPC), and circular dichroism (CD). The multifunctional chiral metasurface realizes AT with more than 70% efficiency over a frequency range of Ku-band from 14.3 to 15.8 GHz, while in the operating frequency band from 13.5 to 16.2 GHz, the CPC ratio is above 90%. In addition, the metasurface exhibits CD in the K-band with a CD parameter of 0.6 at 24 GHz. Furthermore, the functionalities of AT and CPC are stable for changes in incident angle up to 60° for both transverse-electric (TE) and transverse-magnetic (TM) electromagnetic (EM) waves. For verification of the anticipated concept, the proposed chiral metasurface is fabricated and measured. The proposed design can be used for potential applications in the Ku- and K-bands for satellite communication and radar.

“…Efficient control of polarization has always been the focus of researchers. In general, the unit structure of metamaterials/metasurfaces is properly designed, the required polarization control function can be achieved in different frequency bands [1][2][3][4][5][6][7]. Compared to ferrite materials, metamaterials/metasurfaces have the advantages of low mass and small volume.…”

To solve the time-consuming and complex design problems, the deep learning method is used to realize the inverse predictive design of a transmission-type linear-to-circular polarization control metasurface (TLCPCM). Firstly, the target-generation neural net-work model (TGNNM) is constructed based on a fully connected neural network (FCNN). The model selects the critical features of the required electromagnetic perfor-mance as design targets, and maps low-dimensional design targets to high-dimensional electromagnetic performance. Secondly, taking the output data of the TGNNM as input data, an inverse-mapping neural network model (IMNNM) is constructed by a convolu-tional neural network (CNN). The prediction performance of the IMNNM is compared with two other inverse-mapping models. The research results show that the IMNNM out-performs the other two networks. Finally, combining TGNNM and IMNNM, four sets of TLCPCM structural parameters are predicted. The research results show that the elec-tromagnetic performances of the metasurface determined by the predicted structural parameters are generally consistent with the given design targets. On this basis, one ex-perimental sample is manufactured. The measurement results are consistent with the simulation results. The research results demonstrate the validity and feasibility of the inverse predictive design method proposed in this paper.
