Electromagnetic Design System (EMDS) is a commercial finite element method solver for electromagnetic structures from Eesof. EMDS can perform electromagnetic simulation of arbitrarily-shaped, passive three-dimensional structures. It is aimed at providing 3D EM simulation to designers working on RF circuits, MMICs, PC boards, modules, and signal integrity applications. It provides a full 3D electromagnetic field solver, a solid modeling GUI, and fully automated meshing and convergence capabilities for modeling arbitrary 3D shapes such as connectors, machined parts, components, bond wires, antennas, and packages.
