Kinetic equation of Green's function is solved by using method of finite difference and wave-function is calculated from greens function and source term. All possible transitions from bound level of quantum dot to any higher continuum level existing in either quantum well or barrier are taken into account. Trace of peak of absorption co-efficient with gradual change of height to base ratio of quantum dot is simulated under various polarization of incident light.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130476038","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}

Moreover the implementation of this detector using XILINX System Generator software is presented and some features such as cost, flexibility and speed have improved in comparison with the customary detectors. Meanwhile we have estimated the required hardware for the implementation of the JNAM detector using SPARTAN 3 FPGA chips (3s400pq208-5). A comparison between CA-CFAR and the JNAM detector in implementation view point have been done and the results illustrated good performance of the proposed detector.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125445853","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}
