Replacing realistic materials and structures by their ideal counterparts, canonical surfaces, is of great interest for initial and conceptual electromagnetic (EM) studies. The recently introduced DB boundary is defined by a set of simple boundary conditions forcing the normal components of the D- and B- fields to be zero at the boundary. We show that this DB boundary produces many 2-D scattering results that are similar to how practical so-called electromagnetic bandgap (EBG) surfaces behave within the bandgap. Still, it is not directly useable as a canonical EBG surface, because, as we demonstrate in this paper, it is incomplete, creating an anomaly for normal incidence which causes unphysical field solution for 3-D field problems. We have removed this anomaly by introducing the PMC-amended DB boundary. This works in the same way as a practically realized EBG surface for both 2-D and 3-D problems within the bandgap, and is therefore a canonical EBG surface.

Perfect electric conductor (PEC) is often replacing conducting materials in electromagnetic computations, at least during initial and conceptual studies. Similarly, it is possible to replace metamaterials by their ideal counterparts. The latter are herein referred to as canonical surfaces. The use of canonical surfaces will strongly reduce computation time during initial analysis and proof of concept when searching for new metamaterial applications. The canonical surfaces are herein considered to include PEC, PMC (Perfect Magnetic Conductor), PEC/PMC strip grids representing soft and hard surfaces, and the recently introduced DB surface, which is believed to represent an ideal electromagnetic bandgap surface. The paper discusses the characteristics and limitations of these different canonical surfaces, and emphasizes the need for having them available for use in commercial electromagnetic codes.
