To realize an excellent four-way power divider with ideal zero amplitude and phase difference in the four output ports, the whole structure is assumed symmetric with respect to the input port. It operates at E-band with a relative bandwidth of 20.8% and the isolation is lower than -20dB. The signal incident on the input port can be fully, evenly, and in-phase coupled to the output port. Good performances show the proposed power divider a good candidate for terahertz radar and communication applications.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130462904","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 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":null,"pages":null},"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 miniaturized reflective metasurface unit cell is designed for covering the frequency bandwidth range from 10.27GHz to 19.44GHz. 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. This paper shows that the proposed metasurface array can generate stable and high-purity vortex beam in the whole bandwidth.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126731277","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}
