For the multilayer negative-index optical metamaterials, the improved algorithm is competent instead of the traditional one due to the calculation involves a branching problem, and the K-K relations can be applied to remove the problem.","PeriodicalId":421574,"journal":{"name":"2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"74 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124970538","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}

There are lots of recognized methods using HRRP, most of them use the amplitude information for radar target recognition, while the phase information is ignored. In fact, during the recognized processing, the phase information has great advantages to recognition. This paper gives a new method based on the relative phase information. The relative phase is extracted from the target echo by data mining technique. In the recognition experiment, the simulated data of rotation model is used to confirm the feasibility of this new method. At the end, we conclude that this method can eliminate the initial phase sensitivity when the target has little translation.","PeriodicalId":421574,"journal":{"name":"2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125251009","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 three different arrangements correspond to the cases where, firstly the open sides of the two HMSIWs face each other; secondly they share the linear array of metallic vias at their closed side; and thirdly the open side of one HMSIW faces the closed side of the second one. As a reference, the mutual coupling between pairs of parallel microstrip lines is also measured and compared to corresponding HMSIWs. The investigation shows that the best isolation can be achieved for the third configuration. The presented results and comparisons are of importance to the application of HMSIWs in the design of microwave integrated circuits (MICs) and array antenna feeds.","PeriodicalId":421574,"journal":{"name":"2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125310779","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 filter is comprised of a slotline ring resonator, which forms an ultra-wide passband with four resonant modes. Two pairs of defected ground patches are added to improve the desired passband. To achieve a wide upper stopband, a pair of defected ground dumbbell units is introduced. Moreover, a notch band is added around 5.5GHz using a U-shaped slotline to avoid wireless local-area network (WLAN) signals. Finally, a filter is fabricated and tested. Simulated and measured results are in good agreement to exhibit that the proposed UWB BPF has a passband from 3.1GHz to 10.9GHz with a notched band in 5.5GHz, and a wide upper stopband with attenuation level of -12.8 dB up to over 30GHz.","PeriodicalId":421574,"journal":{"name":"2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129858970","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}
