EMAP5 is a full-wave electromagnetic field solver that combines the method of moments (MOM) with a vector finite element method (VFEM). It employs the finite element method (FEM) to analyze a dielectric volume, and employs the method of moments (MoM) to solve for currents on the surface of (or external to) this volume. The two methods are coupled through the fields on the dielectric surface.

EMAP5 can model three kinds of sources: incident plane waves, voltage sources (in the moment-method region) and impressed current sources (in the finite element region). This general purpose code can be applied to a large class of problems where the radiating structures are of the order of a wavelength. However, the ultimate objective behind the development of the code is to efficiently model heterogeneous and arbitrarily shaped dielectric bodies attached to one or more conducting bodies. A typical example of such structures is a printed circuit board (PCB) attached to long wires or cables.
