In particular, in order to obtain a nonlinear behavior of the SRR, we load its external gap with a pair of Schottky diodes, which require a not negligible power level to be activated. Inserting the resulting nonlinear resonator inside the throat of a horn antenna, we show that both matching and radiating properties exhibit or do not exhibit a notched-band, depending on the operating power level.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132164379","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}

Two different forms of low-dimensional eigenstate implementation, each in evanescent and propagating wave regime will be discussed, which are determined by the relative magnitude of plasma and characteristic frequency.
