The filter is based on a reentrant structure with unequal dielectric constants for the internal and external fillings. As a result, additional symmetrical transmission zeros are generated in the lower and upper stop bands of the bandpass filter; this leads to an elliptic function response and improvement of the pass band and selectivity. Similar conclusions are made about the bandstop filter in terms of the return loss. The general TEM circuit model, in terms of the two-port series connection, is presented for the proposed filters, and then, it is used to determine its electrical parameters. The experimental prototype was fabricated using conventional printed circuit board technology. The measured S-parameters show acceptable agreement with the analytical and full-wave simulations, showing promising potential for different applications.</p></div>","PeriodicalId":100999,"journal":{"name":"Pacific Science Review A: Natural Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.psra.2016.09.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79994135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present era of climate change, it is necessary to understand the local impacts of such relationships. In this study, we attempted to portray local climate change using its altitudinal factor and fifteen years (2000–2014) of daily diurnal data from 20 stations in West Bengal, India that experienced increasing summer temperatures over the last several years. The study region is a combined zone of the plateau and plain region where there are variations in altitude. Further, the study used the ARMA model to forecast future climatic conditions of the region. The results demonstrate that climate change is playing an active role in the region, although there was not a convincing relationship between elevation and climate change. The low-lying counterparts of the study area were influenced by climate change. As per the forecast, the gap between the daily maximum and minimum temperatures will generally remain similar to or slightly less than the present conditions, while there is a high possibility of a more prominent decrease in the diurnal temperature range (DTR) over time.</p></div>","PeriodicalId":100999,"journal":{"name":"Pacific Science Review A: Natural Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.psra.2016.11.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91761050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
