Our research in Computational Electromagnetics
Computational electromagnetics (CEM) techniques have become increasingly important with the rapid advancements in technology in areas such as electromagnetic compatibility, antenna analysis, radar signature prediction, cellular phone-human body interaction, design of electrical and medical devices, target recognition and lightning strike simulation.
Electromagnetic phenomena are governed by the Maxwell equations, which can be expressed in either the frequency or the time domain.
Our own work is focused on the numerical approximation of Maxwell’s equations using finite-element technology. The computational solution of problems in electromagnetism presents considerable challenges at both low and high frequencies.
In low frequency problems there are considerable challenges in resolving the thin skin depth, a problem akin to the boundary layer in fluids. In high frequency electromagnetic problems the numerical simulation of electromagnetic wave propagation problems, involving realistic industrial geometries and wave frequencies, poses a significant computational challenge. In order to address these problems, various sophisticated numerical techniques are currently being investigated.
