Research Topics

My reseach topics focus on several aspects related to the computational electromagnetism:

• Subcell  Methods: My research expertise is centered on the development and implementation of subcell methods in computational electromagnetism, specifically within Finite-Difference Time-Domain (FDTD) simulations. I investigate how to effectively model fine-scale features, such as thin layers, that challenge traditional grid resolution. By applying subcell techniques, I enhance the precision of simulations while maintaining computational efficiency, allowing for accurate representations of complex electromagnetic phenomena.

• Human Phantoms: My research interest also includes the use of human phantoms in the FDTD method, focusing on simulating the electromagnetic fields interact with human tissues. This area of study is crucial for applications such as medical imaging, radiation therapy, and bioelectromagnetics. This research is instrumental in assessing the safety and effectiveness of electromagnetic devices and therapies, ultimately contributing to advancements in healthcare and medical technology. 

• Magnetic Materials: I focus on the simulation of magnetic materials in the FDTD method, utilizing the Landau-Lifshitz-Gilbert (LLG) equation. This approach enables the accurate modeling of the dynamic behavior of magnetic materials under the influence of external electromagnetic fields. By integrating the LLG equation within the FDTD framework, we can effectively capture phenomena such as magnetization dynamics, spin-wave propagation, and the response of magnetic materials to varying field conditions. This research is essential for understanding and optimizing the performance of magnetic devices, contributing to advancements in areas such as data storage, magnetic sensing, and spintronic applications.
