Short summary

Apertures in shielding enclosures are an important issue for determining shielding efficiencies. Bethe’s theory describes the coupling via field excited dipole moments at the location of the aperture. This approach neglects the reaction of the dipoles on the exciting field and therefore violates energy conservation. This work emphasizes an analytical asymptotic approach for coupling between half-spaces through small apertures, which allows an understandable generalization of Bethe’s theory.
