The Germanium–Tin (GeSn) alloy has been employed as channel material owing to its high mobility which results from the presence of strain. The main obstacle in using GeSn as channel material in devices is very large leakage current. Use of ferroelectric (FE) layer in FEGeSnDGFET leads to steeper characteristics as compared to conventional device resulting in reduced OFF-state current and subthreshold swing (SS). The impact of variation in FE material properties has also been studied on characteristics of FEGeSnDGFET and it has been demonstrated that FEGeSnDGFET exhibits sub-60 mV/dec SS operation for a wide range of FE material properties.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133256312","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}

The designed SSPP based structure is having under layer ground, which actually helps in obtaining the low insertion loss over a wide frequency range in the microwave and terahertz (THz) frequency range. The isolation capability of the proposed SSPPs structure is studied by designing two SSPP transmission lines on a same substrate, and measuring the coupling between two lines by varying the spacing between these individual lines. For a detailed comparison, an equivalent microstrip structure comprising of two similar transmission lines on the same substrate as that of SSPPs structure are designed. The numerical simulation and measurement studies of these two designed structures shows that the proposed SSPP transmission line exhibits low insertion loss, better isolation and better confinement ability over a wide frequency range as compared to the conventional microstrip transmission line having similar dimensions.","PeriodicalId":201571,"journal":{"name":"2018 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131265968","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}

These systems can be the promising candidates for numerous cellular wireless applications. The first configuration presents an ESPAR-inspired mechanical beam steering antenna with high gain and wide bandwidth performance. This antenna can steer the beam of simple monopole antenna in the entire azimuth plane. However, this structure is unable to steer the beam in the elevation plane. Further, metasurface based beam steering configurations are explored. The concept of metasurface is used initially to design linearly gradient metasurface. This structure can modulate the phase of impinging plane wave results into the beam tilts away from normal direction. Further, the radially gradient metasurface based two more structures are presented. These structures can steer the impinging spherical electromagnetic waves in the both azimuth and elevation planes.

The proposed filtenna has an elliptical radiator which is integrated to a bandpass filter to achieve high frequency selectivity along with a compact size. The filter is designed based on a rectangular stub loaded multiple-mode resonator (MMR). Parallel coupled microstrip feed lines backed by ground plane apertures are utilized in the bandpass filter as well as in the integrated filtenna design. The proposed antenna leaves out the need of cascading additional 50 Ω microstrip in between the developed antenna and filter elements and thus making the system more compact.

The imaging system is properly calibrated so as to nullify any reflection from the background medium. The measured scattering data are processed using appropriate algorithms in order to obtain the 2D microwave image of the test area containing the buried objects. A detailed quantitative analysis of various parameters which affect the quality of subsurface imaging such as the frequency of operation, effect of antenna aperture, directivity etc. is performed.
