ABSTRACT

Computational electromagnetics (CEM) deals with numerical methods applied in solving EM problems. It is based on computer implementation of mathematical models of EM systems using Maxwell equations. CEM tools are useful in analyzing and designing power systems, electrical machines, generators, transformers, microwave networks, waveguides, antennas, and aircraft. Application of these methods is not limited to EM-related problems; they find applications in other continuum problems such as in fluid, heat transfer, and acoustics. The best way to review EM theory is by using the fundamental concept of electric charge. EM problems are classified in terms of the equations describing them. The equations could be differential or integral or both. Two theorems are of fundamental importance in solving EM problems. These are the principle of superposition and the uniqueness theorem. Uniqueness theorem guarantees that the solution obtained for a partial differential equation (PDE) with some prescribed boundary conditions is the only one possible.
