This computation is rooted in the construction of electrostatic micromotors. These devices, which are capable of transforming the electric energy into motion analogously to standard electromotors, do not contain any coils or electric circuits that could be destroyed by strong electromagnetic waves. The goal of this computation is a highly-accurate approximation of the distribution of the electric field in a domain containing two electrodes and a thin object placed between them. The problem is plane-symmetric, and Figure B.20 shows one-half of the domain fi.
