Research Interests
My research interests lie in the application of advanced numerical techniques in electromagnetics, with a particular focus on the analysis and design of waveguide-based circuits and antenna systems. I am especially interested in developing efficient computational models to solve complex electromagnetic problems and optimize system performance. Furthermore, I aim to explore the interdisciplinary application of these technologies in biomedical engineering, such as in medical imaging, diagnostic devices, and therapeutic systems. Through this integration of electromagnetics and biomedical technology, I aspire to contribute to innovative solutions that address real-world healthcare challenges.
