The RF Birdcage Coil resonator is designed without using lumped elements, which is able to resonate at 128 MHz for non-invasively 3T Magnetic Resonance Imaging (MRI) system. This resonator has the Leg and End Rings (ERs), which are composed from copper sheets and then they are attached on the inner and the outer of a circular acrylic as a substrate material in order to produce the capacitance of the resonator and to form a suitable RF Birdcage Coil's configuration. The ERs configuration is arranged to create the capacitance at each birdcage's edge. In order to generate a resonant frequency, the ER sheets should be tuned dimensionally to change each capacitance. The Birdcage Builder software is used to design the initial capacitance configuration of the resonator. Once each capacitance value of the configuration is obtained, then the resonator is numerically simulated by using electromagnetic (EM) simulator. The simulated results show good reflection coefficient at 128 MHz with uniform magnetic field strength distribution. In addition, the birdcage coil performance is also investigated by inserting numerical hand and head phantom models into the coil. The results show that the coil with head phantom is slightly shifted to 128 MHz, in comparison with the coil without human head model, which it resonates at 128.2 MHz.","PeriodicalId":127270,"journal":{"name":"2015 International Conference on Quality in Research (QiR)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134576595","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 results showed three types of early degradation which are permanent and are dependent on epitaxial design and GaN buffer quality. The criterion of critical voltage is defined for the onset of degradation when a subthreshold drain current and/or gate leakage current increase significantly in a step source-drain voltage during stress test. It has been found that AlGaN/GaN HEMT devices with GaN cap show higher critical source-drain voltages as compared to non-capped devices. Devices with low Al concentration in the AlGaN barrier layer also show higher critical source-drain voltages. Superior stability and robustness performance have been achieved from devices with AlGaN backbarrier epitaxial design grown on n-type silicon carbide substrate. It is found that high electric field under the gate at the drain side is the main cause of degradation. Consequently careful epitaxial design to reduce high electric field is required. It is also shown that epitaxial buffer quality and growth process have a great impact on device robustness.","PeriodicalId":127270,"journal":{"name":"2015 International Conference on Quality in Research (QiR)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131595164","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}
