Research

Professor Lee’s main area of research is in the development of numerical techniques for electromagnetics. He has concentrated his research on the differential-based techniques such as the finite element and finite difference methods. He has worked on topics such as hybrid methods (combination of low and high frequency techniques), boundary truncation techniques, and error analysis of FEM. He has also been involved in the development of efficient finite element techniques for modeling electrically large objects. His interest in electrically large problems has resulted in his implementation of finite methods on massively parallel multiprocessors. He has applied his methods to numerous applications including electromagnetic scattering from a variety of objects (jet engines, sea ice, plastic mines, etc.), radiation from various types of antennas (wire, microstrip, arrays, horns, etc.), RF coils for high-field magnetic resonance imaging, wave propagation through complex materials, diffuse optical propagation in biological tissue, and high speed circuits.
