Also, terahertz (THz) technology has been intense attraction for the medical applications due to the harmlessness to human body. Although the serpentine shaped metal electrode is used for bio-application electronic devices, it can also gain the electromagnetic characteristics through the resonance of geometrical inductance and capacitance. We therefore conducted a computational study of a serpentine shaped metamaterial (SSM) to investigate the electromagnetic response in THz using by commercial software (CST Microwave Studio). The detailed results will be discussed.","PeriodicalId":425705,"journal":{"name":"2016 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134499110","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}
