The HSS-matrix representation of the VIE dense system has a controlled accuracy. The inversion of the HSS matrix is exact in the sense that the underlying multiplications and additions are exact involving no approximations. Taking into account the rank's dependence with electrical size, the resultant direct VIE solver is shown to have O(N) complexity in memory and O(NlogN) complexity in inversion, irrespective of electrical size. Numerical experiments on large-scale scattering problems involving millions of unknowns have validated the accuracy and complexity of the proposed new direct solver. The proposed inversion algorithm is also applicable to other integral operators.","PeriodicalId":434972,"journal":{"name":"2016 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121672108","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}

Lane-keeping-assist system with camera is available in many cars to keep self-vehicle inside a solid white line, which is one of important systems for self-driving car. However, camera may be difficult to recognize the line in bad weather conditions, while 79GHz UWB radar may recognize the line with ribs. In this paper, the effect of snowfall on the detection performance has been investigated. Next, vehicle location estimation scheme at 79GHz UWB radar is suggested instead of white line where the measurement results of roadside objects such as guardrail, bridge-rail, and pole-corn instead of the line are presented.","PeriodicalId":434972,"journal":{"name":"2016 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122618251","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}

Generally these kinds of train are running at urban area, because of the signal coverage of base station, single mode of mobile network for the train-ground communication may be not reliable, especially when the train runs at the gap between two base stations. In this paper, we designed a multi-mode multi-channel train-ground communication system by fusing the public 2G/3G/4G mobile networks. The system can use the three kinds of wireless communication mode, and switch among the mode automatically. A multi-mode adaptive wireless data transmission method is proposed. In which, the multimode wireless communication network access technology integrated with GSM, CDMA2000 and WCDMA, TD-SCDMA, TDD-LTE and FDD-LTE are studied and a multi-mode multi-channel model is established to estimate channel. It uses the analytic hierarchy process (AHP) and entropy value method for channel selection according to the channel quality of the predicted and the current detection. Then the data from multiple resources (TCMS, PIS, CCTV) are packed and transported in different ways. The bandwidth of the multi-mode communication links can be effectively used and the online transmission of TCMS information, PIS and video and other data of the train are realized. Simulation results are presented to show the feasibility of the proposed multi-mode multi-channel adaptive transmission method.","PeriodicalId":434972,"journal":{"name":"2016 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121530011","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}

These corner cuts are employed not only to achieve the desired coupling degree between degenerate modes in a single rectangular cavity, but also to create the expected cross-coupling effect for improvement of out-of-band rejection skirt. Based on this triple-mode cavity, a double-cavity filter with five poles is designed. In order to improve the out-of-band rejection and harmonic suppression, a coaxial cavity is further inserted into the two triple-mode cavities to realize a bandpass filter with six in-band transmission poles. Simulated frequency responses are well confirmed by fabricating a prototype cavity bandpass filter and testing its two-port S-parameters.","PeriodicalId":434972,"journal":{"name":"2016 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122175444","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}

Relying on a worst-case error tolerance model, this paper proposes the particle swarm optimization (PSO) as an approach of the worst-case sensitivity analysis (WCSA). The proposed method utilizes the absorbing boundary condition in PSO, thereby improving its ability to search the worst-case solution. Numerical tests demonstrate that PSO outperforms GA, vertex prediction, and random search in WCSA problems. The effectiveness of the concepts presented in this paper are examined through the analysis of etching tolerances applied to the design of a 60GHz microstrip patch antenna.","PeriodicalId":434972,"journal":{"name":"2016 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115030093","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}
