Field and dispersion-relation analyses based on numerical EM simulations showed that the designed dielectric PC slabs filter highly overmoded fundamental passband of a sheet beam plasmonic wave structure (staggered grating pair) within a narrow dynamic frequency range of beam-wave synchronism, capable of avoiding various instabilities such as cutoff- and spurious oscillations. Further investigation on the photonic-band-gap (PBG) effect was also extended to the negative index metamaterial (NIM) of split-ring-resonator (SRR) and wire arrays (wire-SRR). It appears that in the composite waveguide a backward plasmonic wave is superimposed with a forward propagating wave, enhancing field intensity at electric and magnetic resonant frequencies. Currently, a beam-wave interaction is being considered with full 3D particle-in-cell (PIC) simulations and RF-test system construction for proof-of-principle (POP) is under way.","PeriodicalId":6353,"journal":{"name":"2011 International Conference on Infrared, Millimeter, and Terahertz Waves","volume":"8 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2011-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86489629","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}
