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. |
