Firstly, a single SIW cavity fed by microstrip-line and L-shape slots with rectangular slot is applied to construct a tri-band BPF. The offset feed-line is used to excite the three resonant modes to achieve the three passbands. The rectangular slot in the SIW is applied to improve the filtering performance. This filter has a very compact configuration, which still remains a good filtering performance. Then, a second order tri-band filter based on the first order tri-band filter is designed and analyzed. Finally, the proposed second order tri-band filter is fabricated and verified by simulations and experiments.","PeriodicalId":342849,"journal":{"name":"2019 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134448742","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}

However, as flexible electronic materials appear and could be more widely applied to the manufacture of electronic devices and systems, such an assumption may not be valid anymore and EM analysis for such objects needs to consider their moving boundaries or changeable shapes. Obviously, the traditional discretization will be very tedious and time-consuming when the boundaries are changeable. We develop a novel scheme to model such objects and it can remove the need of remeshing geometries in numerical solutions. A numerical example is presented to demonstrate the scheme and its good performance has been verified.","PeriodicalId":342849,"journal":{"name":"2019 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128439748","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}

To generate EM waves carrying OAM, the element structure is well-designed and can introduce additional phase to the incident wave. The employed four-layer cascaded metasurface demonstrates a high performance of transmission and complete phase control.
