The variation of electrical properties of the device under annealing condition was analyzed. Geant4 and TCAD simulations were used to analyze the irradiation effect and damage mechanisms. The results show that the threshold voltage has obvious negative drift and the drain current increases after irradiation. The threshold voltage deviation amplitude of the device increases with the increase of irradiation dose, and the maximum deviation is 1.41V. Annealing at high temperatures (80 °C, 120 °C and 145 °C) partially restores the electrical properties, with a 0.49 V restoration in threshold voltage at 145 °C. Geant4 simulations reveal that enhanced Si MOSFET is more susceptible to total dose effects. TCAD simulations of enhanced Si MOSFET devices demonstrate an increase in electric field intensity, trapped electron concentration, and hole concentration in Si and SiO<sub>2</sub> layers with the increase of irradiation dose. These findings can provide support for the space application and irradiation hardening of cascode GaN HEMT devices.</p></div>","PeriodicalId":101177,"journal":{"name":"Space Solar Power and Wireless Transmission","volume":"1 1","pages":"Pages 61-68"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950104024000051/pdfft?md5=1fdf46f05dde150539cff90df2291bb8&pid=1-s2.0-S2950104024000051-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141487613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By installing the retrodirective capability on both the generator and rectenna arrays, a feedback loop that produces a high efficiency WPT channel is created. In this paper, we characterize the dynamics of this phenomenon using a discrete-time state-space model based on S-parameters and show that the system can naturally achieve maximum theoretical WPT efficiency. We further confirmed the theoretical analysis through a hardware experiment using a 12-port circuit board with measurable S-parameters mimicking a static wireless channel. The results collected from the hardware experiment show agreement with the proposed theoretical framework by comparing the theoretical efficiency with the measured efficiency and by showing that the collected data points follow the predicted condition to achieve maximum efficiency.</p></div>","PeriodicalId":101177,"journal":{"name":"Space Solar Power and Wireless Transmission","volume":"1 1","pages":"Pages 48-60"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950104024000026/pdfft?md5=f53579b41a02c96b9821f546c050b9ac&pid=1-s2.0-S2950104024000026-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141487614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
