Example text
Therefore, electromagnetic analysis plays an important role in scientific research and engineering design. The problem of electromagnetic analysis is actually a problem of solving a set of Maxwell’s equations subject to given boundary conditions. In this chapter we review briefly some basic concepts and equations of electromagnetic theory that are used frequently in this book. Our emphasis is on the presentation of various differential equations and boundary conditions that define boundary-value problems to be solved by finite element analysis.
Finally, an alternative formulation is presented so that the basic principle of the finite element method stands out more clearly. The finite element analysis of a general one-dimensional problem is described in Chapter 3. The result is then applied to the problem of plane wave reflection by a metal-backed dielectric slab, and also to the differential equation arising from the application of the on-surface radiation condition method to scattering by an impedance cylinder. The first problem illustrates the analysis on a straight line, and the second demonstrates the method’s capability in treating a curved line.
