These papers typically start with a simplified overview of the propogation of electromagnetic waves from a dipole antenna and then launch into a detailed mathe matical treatise associated with a specific problem related to shielding. More often than not, the problem is one of obtaining a specific level of shielding given specific barrier materials and/or configuration. The paper will outline the basic problem, de velops the mathematical model used to predict the shielding and then verifies the results with test data. The necessity of verifying the test results dictates that the assump tions used in the mathematical model can be reproduced exactly in the test configuration. This, in turn, necessitates the use of well definable mathematical models simulating the test configurations. The basic mathematical models used by industry to predict the level of shielding of a given barrier emulates the assumptions used by the authors presenting the papers on shielding. That is, they deal with radiated fields propogated from radiators in which the properties of the wave are known, and the shield is of a homogeneous material that can be considered infinite in size with regard to the specific design under consideration.","PeriodicalId":296335,"journal":{"name":"IEEE 1976 International Symposium on Electromagnetic Compatibility","volume":"17 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113936383","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}

This approach assumes a co-site environment and involves the use of relatively simple scoring formulas for selected EMC parameters, which are linearly combined, with appropriate weighting factors, to calculate FOMs for transmitters, receiv ers, and systems (i.e., transmitter-receiver pairs). The parameters chosen for transmitters included spuri ous emissions, noise near the carrier (i.e., broad band emissions outside the band containing desired modulation components), and iritermodulation products. The parameters chosen for.receivers were spurious re sponses, adjacent-signal interactions, and inter modulation products. The parameter scoring formulas were developed to reflect the frequency spectrum de nied by each parameter. A channel was considered de nied if (S + N + I)/(N + I) < 10 dB in a moderately dense co-site environment. The weighting factors for the building-block approach were determined by run ning a computer program .that kept track of the number of channels denied by each parameter.","PeriodicalId":296335,"journal":{"name":"IEEE 1976 International Symposium on Electromagnetic Compatibility","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131993349","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}
