A physical structure in [[EM.Cube]] in made up of a number of geometric objects you either draw in the project workspace or import from an external CAD model file. In [[CubeCAD]], geometric objects are grouped together simply by their color. They do not have any physical properties. However, in all of [[EM.Cube]]'s computational modules, you need to assign physical properties to each geometric object. In these modules, the geometric objects are grouped together by their common physical properties. The physical properties may differ in different computational modules, but they are typically the same as the material properties or related boundary conditions.

From an electromagnetic analysis modeling point of view, materials are categorized by the constitutive relations or boundary conditions that relate electric and magnetic fields.     [[EM.Cube]] offers a large variety of material types listed in the table below:
