Using Maxwell’s equations and volume equivalence principle, the equivalence between the ES-WET and PT is proved rigorously. The equivalence provides a clear physical explanation why the external impressed and environmental fields are treated as a whole–incident field–in the scatterer-oriented characteristic mode theory. In addition, the equivalence between the partial-structure-oriented work-energy theorem (PS-WET, which governs the working process of lumped-port structures) and PT can also be proved similarly. Thus, it can be concluded that work-energy theorem (WET, which is the collective name of the ES-WET and PS-WET) and PT are equivalent to each other.","PeriodicalId":293734,"journal":{"name":"2022 International Applied Computational Electromagnetics Society Symposium (ACES-China)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114219046","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}
