The electromagnetic (EM) wave propagates from the CPW, and then radiates from the probe into the WR4. The rectangular patch is adopted as the probe to accomplish a broadband performance without an impedance transformer. The presented transition has 41.8% fractional bandwidth, which covers the whole WR4 band (170-260GHz). The insertion loss is less than 0.47dB. In addition, the interdigital-pin EBG structure is added to the machining splitter of the rectangular waveguide which is no need for strict electrical contact. The greatest advantage of the interdigital-pin lattice has a significant pin gap increase and is easy to fabricate for millimeter-wave (mm-Wave) applications.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122357465","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}

This method allows designing bandpass filters with tunable central frequency and constant absolute bandwidth. A set of inductance and capacitance values for the center frequency and absolute bandwidth requirements are optimized by using neural network. Then, optimize the capacitance values to adjust the center frequency with fixed inductance values remain unchanged. Experiments show that this method can optimize multiple LC circuit parameters of BPFs with the same absolute bandwidth and different center frequencies effectively and accurately.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125866825","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}

Therefore, a “Zero-Shot” super-resolution CNN framework, which is trained only by the input image itself, is proposed to cope with those degradation factors. With this unsupervised framework, the restoration level of the CNN can be flexibly adjusted based on the input THz image in order to achieve the best restoration effect. Experimental results on both the simulated data and real tested THz data have proved the effectiveness of our method.","PeriodicalId":207010,"journal":{"name":"2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"495 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125829776","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, EIM is a biomarker of muscle status, and its sensitivity is influenced by skin and fat. To restore the impedivity of the muscle layer from EIM data, we use the ICA and EASI algorithms to estimate the impedivity of each tissue layer and compare the performance of ICA and EASI methods. The results showed that the EASI algorithm can better restore the muscle impedivity with an accuracy rate of 0.999.
