The proposed designs are mainly based on generating identical copies of original elliptical dipoles and then shifting the copies horizontally or vertically. The original elliptical dipoles and the shifted copies are merged together to obtain two novel shapes of nanoantennas with high harvesting efficacy. The proposed design offers total harvesting efficiency of 64.7 %; with an improvement of 85.9 % over the conventional rectangular dipole nanoantenna.","PeriodicalId":101990,"journal":{"name":"2016 IEEE/ACES International Conference on Wireless Information Technology and Systems (ICWITS) and Applied Computational Electromagnetics (ACES)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123782819","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}

We utilize sequential approximate optimization where local response surface approximation (RSA) models are constructed and optimized to yield a sequence of designs that converge towards the optimum. The junction geometry is parameterized using splines. In order to reduce the design cost, dimensionality of the design space is gradually increased by adding the number of control points for the spline curves in the subsequent algorithm iterations. The final design exhibits transmission of over 49.5 percent and return loss below 0.3 percent over the wavelength range from 1500 nm to 1580 nm.","PeriodicalId":101990,"journal":{"name":"2016 IEEE/ACES International Conference on Wireless Information Technology and Systems (ICWITS) and Applied Computational Electromagnetics (ACES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116839904","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}
