They are also used to suppress unintended radiations in consumer electronic products (so that they present conformity to existing regulations) and other applications. Their characterization usually shows the amount of damping in a certain frequency range, and it depends on the materials used in the mixture and its overall geometry. This article deals with Brazilian and international manufactured, low cost absorbing materials, characterized in both bulk format (damping) as well as its material parameters (electrical permittivity and magnetic permeability).","PeriodicalId":359348,"journal":{"name":"2014 International Telecommunications Symposium (ITS)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131156852","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 technique is founded on the use of an auxiliary generator and several multi-harmonic loads based on Arbitrarily Width-Modulated Microstrip Lines to ensure the convergence of the optimization process. A 2.5 GHz high efficiency VCO has been designed and synchronized with an external signal. Then, a detailed analysis of the efficiency of all the possible synchronized solutions of the injection locked VCO is presented. Finally, to validate the technique, a prototype has been implemented and experimentally characterized, obtaining a good agreement between the simulated and measured results.","PeriodicalId":359348,"journal":{"name":"2014 International Telecommunications Symposium (ITS)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129819422","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}

It is shown that optimal assignment policies exist under awareness of the traffic profile. For instance, if the traffic rates decrease with the number of requested slots, greedy policies that accept all requests that may be accommodated will speed up the spectrum exhaustion. On the other hand, if the traffic rates increase with the number of requested slots, spectrum exhaustion is favored by wholesale policies that accept only requests for the entire available spectrum. An optimal algorithm is derived for any given traffic profile.","PeriodicalId":359348,"journal":{"name":"2014 International Telecommunications Symposium (ITS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134007755","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}
