In this paper, we demonstrate that a metal encased mobile device is enabled for efficient wireless charging using a loosely coupled resonant system. To facilitate this approach, three coils are designed and distributed on a metal phone case and they are tuned for resonance at 6.78MHz. With electromagnetic analysis of the coil geometry, a prototype is fabricated by machining an aluminum. Measurement results show that 8W can be delivered to the load on a regular AFA (AirFuel Alliance)-resonant compatible charger. In practice, using all three coils is optional and a designer may use only one coil for the metal cover design.","PeriodicalId":113182,"journal":{"name":"2016 IEEE Wireless Power Transfer Conference (WPTC)","volume":"26 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":"121115693","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}

However, these receivers may have different charging requirement, due to the distance between transmitter and receiver, device type and energy demand. Simultaneous charging can also lead to poor comprehensive wireless charging efficiency. We propose a charging priority for the devices in the charging area, considering the device type (in terms of the battery capacity), energy demand, distance to the transmitter, and their movability. This algorithm can enhance the efficiency for more than 20% by charging in order.","PeriodicalId":113182,"journal":{"name":"2016 IEEE Wireless Power Transfer Conference (WPTC)","volume":"12 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":"125323686","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}

A generalized polynomial chaos expansion - being a state-of-art surrogate modeling method - is used to reduce the computational cost involved by these stochastic simulations.
