It was developed by coupling dual-band resonators (DBRs) oscillating at the practical frequencies of 433 MHz and 900 MHz.

Furthermore, when two 20×20 mm2 DBRs are separated by 18 mm, the power transfer efficiency was measured to be around 60% for both operating bands. Finally, the obtained bandwidth of 9 MHz at the data transfer band allows allocating several resource blocks.","PeriodicalId":371560,"journal":{"name":"2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127230039","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 experiment emulates the clinical scenario using a single-tissue anthropomorphic head phantom and strokes with both 20 cm3 and 60 cm3 ellipsoid targets.
