By applying a variational restriction procedure the unknown coefficient functions are determined as an optimum approximation of the true vectorial mode profile.

It is shown that in the case of relatively short optical fibers such as used in sensors, the characteristics of particular light source, evolution of light distribution along the optical fibers, and finite non-homogeneity of plastic material have a significant effect on sensor characteristics.","PeriodicalId":141554,"journal":{"name":"2008 12th International Conference on Mathematical Methods in Electromagnetic Theory","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126662643","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}

It is shown that the coupling between plasmons and THz radiation in the FET array can be strongly enhanced as compared to a single-unit FET due to excitation of the cooperative plasmon mode distributed over the entire area of the FET array. The higher-order plasmon modes revealing the plasmon resonances at frequencies up to 20 THz can be excited much more effectively in the array of FET units with separate channels and combined source and drain contacts.","PeriodicalId":141554,"journal":{"name":"2008 12th International Conference on Mathematical Methods in Electromagnetic Theory","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126412280","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}
