The extreme intense near field of spoof surface plasmons (SSP) on the corrugated metal surface makes it attractive to develop novel electronic sources and many other compact devices in THz regime. In this paper, we propose and investigate a new spoof plasmonic waveguide composed of roofed metallic grating both theoretically and numerically. The theoretical result is verified by numerical simulation of finite integration method both for 2-D and 3-D structure and good agreement is realized. Dispersion and propagation losses of SSP mode on this structure with various structures are also studied and analyzed at THz frequencies (the real copper is used). We find that the roofed metal plate can make profound influence on SSP dispersion characteristics and propagation losses compared with that of opened structure thus should be considered carefully for practical applications. Decreasing the location of top metal plate can induce larger propagation losses of bound SSP mode. Other parameters are similar with that of opened grating which are also considered in the presence of roofed metallic plate. Our complete studies of this roofed metallic grating pave the way for a variety of potential applications such as low-loss waveguide, compact filters, high-efficiency antenna and efficient electronic sources in THz regime.","PeriodicalId":163276,"journal":{"name":"2020 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124358142","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}

In dual-band FPA, a dual-band filtering network synthesis technique is proposed. It includes two steps: building impedance transformation network (ITN) with transmission zeros pair (TZP) to generate dual-band filtering performance and utilizing synthesis technique to obtain the structure parameters by making the fundamental and the second harmonics matched at the two passbands. For demonstration, a single-band FPA with wide bandwidth of 31.1% is implemented and measured.

Within this design, TE102 and TE201 are two dominant modes inside each cavity and each correlates with one passband responses. Due to their symmetric field distributions, balanced inputs/outputs can be assigned.
