Abstract
Electromagnetic band-gap substrates o er advantages regarding cross-coupling in sub-mm range imaging
array applications. Electromagnetic scattering by such substrates may e ectively be formulated in terms of integro-
di erential equations. The scattered elds are evaluated via the spectral domain in which the 3-D problem reduces to
an in nite system of coupled 1-D integro-di erential equations ...

Electromagnetic band-gap substrates o er advantages regarding cross-coupling in sub-mm range imaging
array applications. Electromagnetic scattering by such substrates may e ectively be formulated in terms of integro-
di erential equations. The scattered elds are evaluated via the spectral domain in which the 3-D problem reduces to
an in nite system of coupled 1-D integro-di erential equations. The associated matrix-vector products are dominated
by FFTs. For moderate frequencies an elementary preconditioner in combination with a prudent initial estimate usually
su ces to reach rapid convergence using the transpose-free quasi-minimal residual method. [--]
