We experimentally demonstrate a record-high pulsed terahertz radiation power of 4 mW and a radiation bandwidth of 0.1–5 THz, exhibiting one order of magnitude enhancement in radiation efficiency compared to the state-of-the-art.","PeriodicalId":264754,"journal":{"name":"2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125883042","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 the TR-MPT system, the Time-Reversal Mirror (TRM) array receives detecting signals emitted from the targets and re-emits the time-reversed one convoluted with high energy electromagnetic waves, and then the electromagnetic wave energies are focused on the targets. Three cases with different target positions are studied. Compared to the energies received by the targets in a conventional MPT system, more energy can be received by the targets in the TR-MPT system. The results show that the TR technology can be used to improve the performance of a multi-target MPT system.","PeriodicalId":264754,"journal":{"name":"2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126028446","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 work, Chebyshev linear arrays are considered. We start from identifying candidate CFs. Numerical optimization of the fast CFs models allows for identifying the best architecture in terms of accuracy of realizing the required amplitude excitations, as well as finding the set of power split ratios of the junctions within the CF. The junctions of the best CF architecture are then implemented and tuned using a discrete full-wave modeler (solver). CF validation and tuning is also conducted at the full-wave simulation level. Finally, the entire aperture-feed circuit is validated with simulations. Our approach is illustrated using twelve element Chebyshev arrays where the quantities of interest are sidelobe level and reflection coefficient.","PeriodicalId":264754,"journal":{"name":"2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116050473","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}
