It is designed to cover a very wide frequency range from 1 to 10 GHz. The proposed antenna is formed by a feeding microstrip line terminated with a metallic via on the top layer and a tapered slot antenna transitioned by a slot line terminated with a circular slot cut on the bottom layer. The performance of the antenna is evaluated both in time and frequency domain, the measured result shows good agreement with the simulation. The antenna is well matched and the realized peak gain varies with frequency, which can compensate for path loss during propagation, and the narrow time impulse response indicates a short group delay. It is suitable for ultrawideband short-range positioning application.","PeriodicalId":274385,"journal":{"name":"2020 13th UK-Europe-China Workshop on Millimetre-Waves and Terahertz Technologies (UCMMT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124069157","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 this scheme, an electron beam passes through a plasma section and interacts with self-excited nonlinear plasma wake to gain a periodic “sawtooth” energy modulation. Such energy modulation is then effectively converted into a beam density modulation by means of magnetic optics forming microbunches with a high charge up to a few nC and a bunching factor as high as ∼0.8. A tunable tens to hundreds of mJ level narrow-band THz radiation could be generated. This scheme can be realized in future accelerator facilities with repetition rate on the order of kHz to MHz, which provides great potential in modern science and related technologies.","PeriodicalId":274385,"journal":{"name":"2020 13th UK-Europe-China Workshop on Millimetre-Waves and Terahertz Technologies (UCMMT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130429561","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}

However, the THz waves with the characteristic of strong directionality are easily blocked by indoor obstacles, leading to a communication interruption. To this end, an intelligent reflecting surface (IRS) is considered in THz multiple-input multiple-output (MIMO) systems. In this paper, an efficient artificial gene reservation aided genetic algorithm, namely AGR-GA, is proposed by reserving the good genes and eliminating the inferior genes during the iterative process. Simulation results demonstrate that, in contrast with the exhaustive search scheme, the AGR-GA slightly endures 0.98 bps/Hz performance compromise with negligible complexity.","PeriodicalId":274385,"journal":{"name":"2020 13th UK-Europe-China Workshop on Millimetre-Waves and Terahertz Technologies (UCMMT)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133054947","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}
