The previous algorithm takes into account the multiple reflections of the radio wave inside the obstacle and this method can calculate these propagation processes under the calculation framework of the 2W-PE by fitting with multiple ANNs, which greatly accelerates the computational speed of spatial field value prediction in the obstacle environment. In addition, due to the complexity of the environment, it is difficult to determine the boundary condition coefficients of obstacles in the calculation, so we apply a non-end-to-end trained ANN. The simulation results show that this method can greatly increase the calculation efficiency.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127938006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incident plane waves can be converted into vortex waves carrying orbital angular momentum by the unit surface, which keeps a more than 90% polarization conversion efficiency in working bandwidth. In compare with other metasurface unit cells, the designed bow-tie shaped structure has the advantages of high conversion efficiency, small size and broad bandwidth. The reflective arrays are designed for generating the vortex beams with the topological charge of -1, -2 and -3, which are constructed by rotating meta-atoms. The corresponding energy weight analysis and near-field electric field distribution of each reflected vortex wave are achieved by numerical simulation to verify the high performance of the designed metasurface.
