Abstract

A new iterative method based on waves concept of planar inductor and the coupling of two inductors for different coupling distances was studied and modelled. The formalism of the mathematical operators was applied. The contribution of the Fast Fourier Transform allows to accelerate the digital processing in order to have electromagnetic information on each pixel of the discretized circuit plan. The software implemented initially permit calculation of the current density or electric field in the circuit locked up in a metal case. From this study the result will lead to the determination of the ' S ' parameters modeling the coupling of the spiral inductors without neglecting the compensation by an air bridge with the intersection on the same plan of the inductor drivers.
