EM.Libera is a 3D free-space structure simulator for modeling metallic structures. It features a full-wave Method of Moments (MoM) engine for analyzing wire structures or wire-frame models of metallic surfaces and solids. Many RF systems utilize wire antennas like dipoles, monopoles, loops, or arrays of wire antennas. The 3D method of moments (MoM) based on Pocklington's integral equation can accurately model such antennas and their coupling effects. Moreover, in many applications, metallic surface or [[Solid Objects|solid objects]] can be approximately modeled as wire-frame structures. EM.Libera's Wire MoM simulator can provide an adequate numerical solution of wire-frame structures. Examples of this sort are wire antennas in the presence of large reflectors or scatterers. Wire-frame models also make a good approximation of metallic target structures for radar cross section (RCS) analysis.

EM.Libera's Wire MoM simulator is seamlessly interfaced with EM.CUBE's other simulation engines. The solution of a wire-frame structure can be imported to EM.Cube's other modules as a set of short dipole sources with proper amplitudes and phases.
