EM.Libera is a 3D free-space structure simulator for modeling metallic and dielectric structures. It features a two 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 dipolessimulation engines, monopoles, loops, or arrays of wire antennas. The [[3D Method of Moments|3D method of moments]] (one based on a Wire MoM) formulation and the other based on Pocklington's integral equation can accurately model such antennas and their coupling effectsa Surface MoM formulation. MoreoverIn general, in many applicationsa surface MoM solver is used to simulate your physical structure, which may involve metallic surface or [[Solid Objects|solid and dielectric objects]] can be approximately modeled of arbitrary shapes as wire-frame well as composite structuresthat contain joined metal and dielectric regions. If your project workspace contains at least one line or curve object, EM.Libera's then invokes its Wire MoM simulator solver. In that case, only metallic structure can provide an adequate numerical solution of wire-frame structures. Examples of this sort be modeled, and all the surface and solid PEC objects 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) analysismeshed as wireframes.

{{Note|You can used EM.Libera's Wire MoM simulator is seamlessly interfaced with [[EM.Cube|EM.CUBE]]'s other simulation engines. The solution of a either for modeling metallic wire-frame structure can be imported to [[EM.Cube]]'s other modules as a set of short dipole sources with proper amplitudes objects and phaseswireframe structures or for modeling metallic, dielectric ad composite structures that do not contain lines or curves.}}
