This approximation leads to a closed-form representation for the Greenpsilas function that is very useful in analyzing the periodic structures such as frequency selective surfaces and meta-materials using the integral equations. Accuracy of the results obtained by the proposed method is shown by comparing with other numerical methods.","PeriodicalId":397229,"journal":{"name":"2007 IEEE Applied Electromagnetics Conference (AEMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120957886","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 inter layer separation and size of the patches of the circularly polarised antenna were optimised by successive simulations using the commercial software. Measured gain flatness was better than 1dB and impedance bandwidth was better than 10% around the centre frequency at X-band.

Man-made EM1 is on the increase daily, due to the increased use of electrical and electronic equipment. The successful detection and elimination of EMI require a systematic search for EM1 sources as well as knowledge of interference susceptibilities of the equipment. Familiarity with the environment in which the equipment will work as well as possible alternative environments are fundamental to effective EMI reduction to a required minimum level. In this paper we designed a simple two wire model to predict EMI when this model is illuminated by a distant source antenna. The proposed model is being fabricated at Indian Institute of Technology, India. Measured and simulated results are shown. Simulations were being carried out at Kalpana Chawla Space Technology Cell, IIT Kharagpur, India.","PeriodicalId":397229,"journal":{"name":"2007 IEEE Applied Electromagnetics Conference (AEMC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131127829","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}
