As the efficient part of the circuit fields varies in the angular direction, a 3D tool is needed to model such a phenomena. The numerical model is presented, with some examples of BWO starting conditions research. Close to the π mode, both forward and backward interact with the beam and any coupling of both waves has a strong effect. Consequently the threshold current is lowered. Several causes of coupling have been studied.","PeriodicalId":283300,"journal":{"name":"2013 IEEE 14th International Vacuum Electronics Conference (IVEC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115041495","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}
