A spectral dyadic Green's function of multilayer structure containing arbitrarily biased magnetic layer is developed. A systematic iterative procedure for structure with more than 3 layers is developed by numerical computation of transfer matrix. Applied to practical device such as differential ferrite loaded phase shifter good agreement is obtained between measured and computed results. The use of singularity extraction techniques allows to bypass the numerical truncation of Fourier transform and accelerate the convergence speed.
