Based on the provided discussion, a flexible band-stop scheme is proposed resulting in stabilized shielding effectiveness (SE) both in the nearfield (NF) and farfield (FF). To analyze the NF filtering capability of FSS, some discrete localized electric field probes are placed at different points of the NF zone. The frequency spectrum of the NF signal is extracted for two in-band and out-band harmonics. The final design shows one stabilized transmission zero. The transmission zero attenuation does not significantly change as a function of spatial distance from the FSS. Similarly, the shield does not experience a resonant frequency shift in the NF zone.","PeriodicalId":443426,"journal":{"name":"2020 IEEE USNC-CNC-URSI North American Radio Science Meeting (Joint with AP-S Symposium)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129930593","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}

Though the Markov chain Monte Carlo (MCMC) methods have been extensively used in geophysical inversion, the sampling time can be prohibitively long due to the low efficiency and the sequential property of the methods. The transitional Markov chain Monte Carlo (TMCMC), as an efficient sampling algorithm based-on MCMC, can improve the performance of MCMC and greatly reduce the sampling time. However, this method has not drawn much attention in the geophysical inverse problems. In this paper, we use the TMCMC to infer the underground formation from the electromagnetic well logging data. Since that the TMCMC is naturally suitable for parallel computing, the inversion process takes a much shorter time to achieve a similar result as the traditional MCMC sampling.","PeriodicalId":443426,"journal":{"name":"2020 IEEE USNC-CNC-URSI North American Radio Science Meeting (Joint with AP-S Symposium)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124121232","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}
