Dr. Fernando Albarracin from the Technology Innovation Institute has presented a novel microwave applicator design for hyperthermia, potentially useful in cancer treatment. The design combines two flat dielectric graded-index (GRIN) lenses to localize electromagnetic energy within a specific spot in the tissue. This system offers a suitable alternative to conventional antenna-based applicators by considering the interface between free space and human tissue. Why it matters: This research introduces a new approach to hyperthermia treatment that could improve the precision and effectiveness of cancer therapy in the region.
John Pantoja from the Directed Energy Research Center at TII presented a method to estimate the effects of high current impulses on electro-conductive textiles. The method uses specific action, a parameter to determine burst of exploding wires, and a new equivalent electrical circuit. The model estimates the current intensity needed to melt the conductive layer at contact areas between yarns, and is validated experimentally on ripstop woven fabrics. Why it matters: The research explores conductive fabrics for portable lightning protection shelters, potentially reducing lightning-related accidents in high-risk populations.
Mae AlMansoori from TII's Directed Energy Research Center won the Young Scientist Award at URSI Kleinheubacher Tagung 2020. Her paper introduced a correlation metric to evaluate the influence of random variables on high-power electromagnetic sources, specifically a Vircator model. The study combined extreme value theory and descriptive statistics to analyze peak output power variability and identify dominant factors. Why it matters: The research offers a framework for managing uncertainties in high-power electromagnetic sources and optimizing their efficiency, relevant for defense and energy applications in the region.
The 34th General Assembly and Scientific Symposium (GASS) of the International Union of Radio Science (URSI) will be held in Rome from August 28 to September 4. The Technology Innovation Institute’s Directed Energy Research Center (DERC), led by Dr Chaouki Kasmi, will present a tutorial and five scientific papers. DERC's presentations will focus on advances in electromagnetics and optoelectronics. Why it matters: DERC's participation highlights the UAE's growing role in international radio science research and development.
KAUST Ph.D. student Ghulam Qadir received a best poster award at the GRASPA 2019 conference in Italy. The winning poster, titled "Estimation of Spatial Deformation for Non-stationary Processes via Variogram Alignment," was based on Qadir's Ph.D. research project. The research focuses on developing covariance models for multivariate nonstationary random fields with applications to environmental data. Why it matters: This award recognizes KAUST's contribution to environmental statistics and highlights the university's commitment to advancing research in this area.
