The proposed prototype uses microwave-imaging technology to monitor a brain stroke after its onset, exploiting the different dielectric properties of human tissues. This device complements well-assessed MRI (Magnetic Resonance Imaging) and CT (Computerized Tomography), and could give clinicians fast and extra information in the decision-making stages. The system includes a helmet-like array of antennas, a switching system to connect the antennas to signal processing, the signal processing itself, and the imaging algorithm. The complete functioning prototype reconstructs the position and size of a target - representing the stroke - in a three-dimensional human-like head phantom that considers the proper tissue properties. In this work, different sizes and positions of targets demonstrated the prototype's functioning. Although the system had low complexity, the available information guaranteed a good reconstructed image of the scenario.","PeriodicalId":101270,"journal":{"name":"URSI Radio Science Bulletin","volume":"2021 377","pages":"12-18"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/7873543/9829337/09829344.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50351140","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}

In this context, the URSI General Assembly and Scientific Symposium (GASS) 2021 was conducted in hybrid mode. The Young Scientist (YS) Awards were also granted and the Student Paper Competition (SPC) was held. In this ECR column we feature two short reports on the Young Scientist Awards and the Student Paper Competition.

Advocates of 5G mobile technology hail 5G as a faster and more-secure technology than its predecessor 3G and 4G systems. The major enabling infrastructure uses millimeter-wave (mm-wave) and phased-array technologies to achieve line-of-sight directivity, high data rates, and low latency. A central vulnerability or security threat is that it may allow spying on users. Nevertheless, this is a system architecture and technology or regulatory issue, but not a biological or health safety matter.","PeriodicalId":101270,"journal":{"name":"URSI Radio Science Bulletin","volume":"2021 377","pages":"64-68"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/7873543/9829337/09829356.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50350958","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}

My colleague, Dr. Carol Norberg, and I had attended the conference to present our papers and learn about the latest advances within the areas of expertise of the other participants in preparation for teaching graduate school classes about the space environment around Earth.
