Abstract :
The authors introduce a method for generating closed-form expressions for calculating mutual admittances between slots in a ground plane (magnetic currents). The method is derived in the Fourier domain, and it is shown that it corresponds to a multipole expansion of the coupled distributions. As an example, the aperture distribution and its Fourier transform are calculated for a half-wave slot in a conducting ground plane.<>
