This chapter presents a mathematical formulation of several class of aperture coupling problems between two arbitrary regions through multiple apertures. The formulation is based on the “Generalized network formulation for aperture problems” which is solved using the Method of Moments (MoM). Mainly two different classes of basis functions namely roof top basis function and RWG functions are used in the analysis in order to model regular and arbitrary shaped apertures, respectively. The excitation matrix is formulated assuming waveguide fundamental mode and the uniform plane wave excitation. The aperture characteristics are expressed in terms of the scattering parameters, aperture admittance and transmission cross section.
