Solution of large scale problems has been one of the major challenges of computational electromagnetics. One approach to address this problem is to divide a problem space into smaller subregions and combine the solutions of subregions, after multiple interactions, to achieve the solution for the large domain. Solution of the subregions using frequency domain solvers has been the preferred approach as such solutions using time domain solvers require computationally expensive bookkeeping of time signals. In this contribution we present an algorithm that makes it feasible to use the FDTD method, a time domain numerical technique, in the IMR technique to achieve solutions at a number of pre-specified frequencies.","PeriodicalId":6663,"journal":{"name":"2014 IEEE Antennas and Propagation Society International Symposium (APSURSI)","volume":"17 1","pages":"506-507"},"PeriodicalIF":0.0,"publicationDate":"2014-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84522531","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}

Graphene and its compounds have enabled the development of novel devices for a wide variety of applications in an extremely short period of time. In addition, non-graphene ATLMs have recently been utilized to produce devices with exceptional performances. It is anticipated that ATLMs will play a crucial role in the integration of nano electronics with photonics and plasmonics in the coming decades. However, there are many challenges that need to be addressed before it is possible to convert the potential of ATLMs into reality. Their accurate and efficient modeling is one of these challenges. In this work, I briefly discuss our recent efforts on the development of a hybrid Schrödinger-Poisson and Maxwell's Equations solver that will enable us exploring how light interacts with ATLM systems in different configurations and under different biasing conditions.","PeriodicalId":6663,"journal":{"name":"2014 IEEE Antennas and Propagation Society International Symposium (APSURSI)","volume":"33 1","pages":"1389-1390"},"PeriodicalIF":0.0,"publicationDate":"2014-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85096517","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}
