The ASCAT Level 2 winds climate data record produced by the Royal Netherlands Meteorological Institute (KNMI) and obtained through the EUMETSAT Data Centre covering the tropical cyclones between the year of 2007 and 2012 are being investigated in this study. Each of the ASCAT orbits will be spatially and temporally collocated within 500-km radius and 30-minute time window, respectively, with the tropical cyclone best track data in the North Western Pacific basin obtained from the Joint Typhoon Warning Center. Then the standard wind radii of 34-knot, 50-knot and 64-knot will be evaluated and a comparison with the wind radii reported from the best track will be made. We present a novel wind speed radii characterization technique by computing the normalized wind radii of the storm scenes matchup and then compute a composite of the distribution of the entire North Western Pacific basin. Wind speeds from ASCAT were quality controlled using an appropriate quality flag provided in the data. A statistical ASCAT wind radii performance with respect to the best track will be presented.","PeriodicalId":355217,"journal":{"name":"2018 Progress in Electromagnetics Research Symposium (PIERS-Toyama)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128960541","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}

A larger ratio of mutual inductance to resistance is preferred for MC- WPT system to achieve a higher power transfer efficiency. In this paper, the key parameters including outer diameter of coil, the number of turns and the separation distance between adjacent turns are optimized after the ratio of mutual inductance to AC resistance is analyzed. Based on the genetic algorithm, the optimal parameters to increase the efficiency are obtained when the ratio reaches maximum value. The coil fabricated through proposed optimization method is verified to achieve the highest power transfer efficiency by simulation results, and the optimization method is validated to be feasible by the experimental results.","PeriodicalId":355217,"journal":{"name":"2018 Progress in Electromagnetics Research Symposium (PIERS-Toyama)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129834443","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}

We particularly focus on nanoparticles that are made of typical metals at the lower THz frequencies. Even though the frequency is relatively low, we show that penetrable models are needed for accurately representing electromagnetic characteristics, especially to predict penetrating magnetic fields inside small particles. Due to large permittivity values with negative real parts, stable formulations are needed to obtain equivalent currents and secondary fields. It is shown that the modified combined tangential formulation, which was proposed for plasmonic simulations in wide frequency ranges, provides accurate solutions that are consistent with analytical results for spherical nanoparticles.","PeriodicalId":355217,"journal":{"name":"2018 Progress in Electromagnetics Research Symposium (PIERS-Toyama)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129230164","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}

By decoding the discretized matrix formed by the basic information matrix and the grayscale matrix, we can recover the information matrix that has been damaged and finally to realize the traceability of the goods.
