This article strictly concentrates on the use of the finite‐difference method (FDM) in the numerical analysis of boundary value problems associated with primarily static and to some extent quasistatic electromagnetic (EM) fields. Although all examples presented herein deal with EM‐related engineering applications, some numerical aspects of FDM are also covered.
The emphasis will be placed on the applications of FDM to three‐dimensional boundary value problems involving objects with arbitrary geometric shapes that are composed of complex dielectric materials.
