EM.Cube’s [[Planar Module]] is intended for constructing and modeling planar layered structures. By a planar structure we mean one that contains a background substrate of laterally infinite extents, made up of one or more material layers all stacked up vertically along the Z axis. Objects of finite size are then interspersed among these substrate layers. This is somehow different than EM.Cube's other computational modules, which are geared for handling arbitrary 3D structures.
