Metode Numerik

In the preceding chapters we considered various analytic techniques for solving EM problems
and obtaining solutions in closed form. A closed form solution is one in the form of an
explicit, algebraic equation in which values of the problem parameters can be substituted.
Some of these analytic solutions were obtained assuming certain situations, thereby
making the solutions applicable to those idealized situations. For example, in deriving the
formula for calculating the capacitance of a parallel-plate capacitor, we assumed that the
fringing effect was negligible and that the separation distance was very small compared
with the width and length of the plates. Also, our application of Laplace's equation in
Chapter 6 was restricted to problems with boundaries coinciding with coordinate surfaces.
Analytic solutions have an inherent advantage of being exact. They also make it easy to
observe the behavior of the solution for variation in the problem parameters. However, analytic
solutions are available only for problems with simple configurations.
