Computational electromagnetics (CEM) is the field of computational engineering and science that focuses on electromagnetic (EM) phenomena. It provides a cornerstone for many electrical, wireless communication, portable electronics, optical, geophysical sensing and medical instrumentation technologies. Advanced CEM algorithms and simulation tools can significantly contribute to the development of new technologies, expedite the design cycle of new products, save costs and lead to new innovative solutions.
The research of our group covers a large scale of subjects on the integral equation based methods in CEM. We develop well-conditioned and stable formulations and algorithms, investigate novel and efficient discretization schemes and implement fast and hybrid solvers. The numerical methods have been applied in several practical applications such as simulation of mobile phone antennas, shape optimization of UWB antennas, remote sensing of sea and tree, mobile phone acoustics, analysis of large 3D metamaterial structures and other complex EM materials and surfaces, quasi-static eddy current and magnetic modeling, and electrostatics.
