In order to be robust against fading, polarization of the antenna is circular. The antenna includes a crossover slot SIW antenna with a cavity to increase gain and have a better axial ratio. One of the unique advantages of this antenna is covering the area with circularly polarization and adding one port to the antenna that causes to connect with more users at the same frequency. The antenna is simulated with two different methods and the results are verified.","PeriodicalId":338853,"journal":{"name":"2018 Fifth International Conference on Millimeter-Wave and Terahertz Technologies (MMWaTT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115406019","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}

Generally, design of GRIN flat lenses calls for segments with very specific tailored permittivity which makes the realization of the lens challenging. To facilitate fabrication of the lens, each segment is replaced with a same-thick symmetric three-layered structure consisting of a layer of high permittivity material which is sandwiched between two low permittivity layers. Silica and silicon are utilized as low and high permittivity materials, respectively. Finally, by increasing the number of layers, a multi-layered GRIN flat lens with an enhanced focusing performance presented.","PeriodicalId":338853,"journal":{"name":"2018 Fifth International Conference on Millimeter-Wave and Terahertz Technologies (MMWaTT)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130208474","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}

DLWAs provide high directive beams and continuous frequency beam scanning, non-fluctuating leakage constant and real non-zero Bloch impedance at and around broadside, due to the closed and linear Dirac dispersion relation around broadside. These features, along with their inherent compatibility for higher frequency designs (larger unit cells compared to metamaterials), make DLWAs an ideal candidate for the upper microwave, mm-wave and terahertz frequencies, and for applications such as radar, 5G, spectroscopy, etc. In this review, we cover the recent developments on Dirac leaky wave antennas, their principles and salient features, and technological potentials of these structures.","PeriodicalId":338853,"journal":{"name":"2018 Fifth International Conference on Millimeter-Wave and Terahertz Technologies (MMWaTT)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126350168","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}

Heat generation density calculated for the bowtie nanostructure at its absorption resonance wavelength of 694 nm verifies efficient concentration of heating power at the bowtie tips, due to optical near-field effects. Total absorbed power for the nanodisk beneath the probe has the same resonance wavelength at 694 nm, which confirms that the temperature increase produced at the underneath nanoparticle is due to utilizing the bowtie nanostructure on top of the SNOM probe as a heat nanosource. Temperature rise of about 680 K, confined to a nanodisk with 10 nm diameter has been demonstrated. Based on these results, the plasmonic SNOM probes can be promising tools for the localized heating in thermally activated processes, such as near-field optical chemical vapor deposition (NFO-CVD).","PeriodicalId":338853,"journal":{"name":"2018 Fifth International Conference on Millimeter-Wave and Terahertz Technologies (MMWaTT)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125199347","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}
