The designed GMR filters have a high Q-factor [1], tunable filter [2], and sensor [3]. It is working depend on refractive index, THz beam incident angle, polarization, GMR filter groves periods, and thickness of GMR core. These GMR filters of experimental results were in good agreement with simulation results.","PeriodicalId":6686,"journal":{"name":"2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz)","volume":"68 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90680593","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}

Despite moderate carrier mobility in CVD graphene (~103 cm2/V/s), the resonance is clearly distinguishable above the Drude absorption background in the 5-10 THz range. The optical scattering time governing the quality factor of plasmon resonance appears to be well above the dc relaxation time. We confirm this relation by simultaneous THz transmission and field-effect measurements. We also show that the presence of the grating coupler in close proximity to graphene modifies the plasmon spectra. The plasmon field becomes tightly bound below the metal stripes, while the frequency depends on the stripe length but not by grating period.","PeriodicalId":6686,"journal":{"name":"2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz)","volume":"13 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89700475","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}
