The research on it has been one of the most active topics in the world. Rectenna is a key component of the MPT system, as well as the main direction of research at home and abroad. At present, most researches on rectennas are large-scale array antennas, of which the rectification efficiency performs well, but the design and implementation can be complicated. For this reason, in this paper, we design a simple meander dipole rectenna of 2.45 GHz for compact and low power, with a rectification efficiency of 40.5%, which is appropriately applied to most compact wireless energy transmission equipment.","PeriodicalId":342849,"journal":{"name":"2019 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127285615","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 nonlinear property of the material is reconstructed and solved based on the parametric quadratic programming method, and domain decomposition strategy with DG scheme is employed to deal with multiscale modeling. By solving the nonlinear constitutive relations as a series of linear complementary problems (LCP), this nonlinear DG-FETD scheme avoids updating the system matrices at each time step and presents a good convergence behavior. The DG method enables the non-conforming meshes between subdomains and also separate the nonlinear and electrically fine structure from other linear subdomains.
