The latest version of the XGtd electromagnetic (EM) simulation antenna modeling software from Remcom is designed for performing analysis of far-field radiation patterns, radar cross sections (RCSs), and electromagnetic interference and electromagnetic compatibility studies on electrically large platforms.Based on Geometric Optics and the Uniform Geometrical Theory of Diffraction, performance and memory requirements are not affected by the physical size of objects, but rather by the number of faceted surfaces used to model them. This makes it ideally suited to applications with higher frequencies or very large platforms where the electrical size of a computation may be too large for full physics techniques, such as Finite Difference Time Domain.Get more information from Remcom.
