Would anyone know the basic equation on which EM simulators are working.
Like Sonnet is based on TLM ,
What about CST, Momemtum (agilent), HFSS, and others...
is it Method of Moments, Finite element Method(FEM) , Finite differential Method ....

Hybrid MoM/UTD means that the problem is solved using the combination of the moment method and the Uniform Theory of Diffraction (UTD). UTD is the same as GTD (Geometrical Theory of Diffraction) and is a high-frequency approximation that uses ray tracing. It assumes a plane wave and is used to calculate scattered fields on electrically large structures (> 10*lambda). Burnside and Marhefka at OSU contributed greatly to the theory of GTD/UTD (determining the correct diffraction coefficients, etc.)
Grasp is a reflector analysis tool that uses physical optics (PO), geometrical optics (GO) and GTD.
Ansoft Designer is another planar (2.5D) MoM code.
