With the evolution of 5G in the sister millimeter-wave band, the field of integrated THz technology has progressed significantly towards enabling efficient and compact Terahertz systems operable at room temperature and deployable at large scales. This has been facilitated by key developments in a multitude of integrated technology substrates in electronics, photonics and also hybrid systems. While fmax of III-V based devices have crossed 1.5 THz, silicon-based THz systems have shown remarkable advancements in complex systems including chip-scale phased arrays, active and passive imagers, and wireless communication systems. While this technological progress has led to steady closing of the ‘THz gap’ in the past ten years, there needs to be concerted effort in closing the ‘THz’ and ‘application’ gap in the next ten years to allow large scale deployment of THz technology. In this paper, we summarize the advancements in integrated THz systems in the past decade, discuss future challenges and directions to progress towards that goal.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132767002","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 proposed design works in X-band. The leaky wave antenna is designed using half-mode substrate integrated waveguide technique, that provides circularly polarized beam. The proposed active integrated antenna consists of a leaky wave antenna section which is cascaded with active device to make a self-oscillating radiating structure. The leaky wave antenna has beam scanning ability by varying the input signal frequency and hence the oscillator section is modified using an active tunable reactance to provide a voltage tunable oscillation frequency to the leaky wave antenna section to achieve automatic beam scanning ability. The proposed active tunable reactance provides wider tuning range than commercial varactor for a small range of variation of tuning voltage. The proposed leaky wave antenna has a wide operating range covering the whole X-band and has axial ratio of better than −4.5 dB throughout the frequency range of interest. The oscillation frequency range provided by the active section is 10.5-10.95 GHz with the variation of tuning voltage from −4 V to −1.1 V. The AICPLWA covers an automated beam scanning range from 34°-40° for the 10.5-10.95 band. The proposed AICPLWA can be used in various applications such as microwave imaging, sensing radars requiring automotive beam scanning module.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133038316","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}

Herein, Magnetite nano hollow spheres (FO NHS) of diameter ~ 285 nm are prepared by template free facile solvothermal method and their magnetic, dielectric and microwave absorption properties are investigated. A minimum reflection loss (RL) ~ −35.8 dB is observed at ~ 11.7 GHz on composite filled with epoxy resin (20 wt% and thickness of 2 mm) with a broad band width of 9-12 GHz frequency region with RL ≤ −10 dB i.e. absorption > 90%. Also, in the studied X-Band (8-12 GHz) multiple peak regions with effective absorption are found. Hollow core of NHS suggests multiple internal reflections of incident wave with higher surface area and lower density. Throughout the frequency region, shielding efficiency (SE) maintains a value < −10 dB and a high value (~ 115) of attenuation constant (α) is observed. These properties of FO NHS make it a promising candidate for applications towards Communication devices, Information security and EMI shielding.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123268606","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}
