Numerical simulation of wave propagation in microstrip line containing magnetic layer

A numerical full wave method has been applied to get the characteristic dispersion of microstrip line containing anisotropic magnetic layer. This method is based on the numerical formulation of the spectral dyadic Green's function by using the transverse operator method in the Fourier domain. Green's function obtained for the stratified multilayer structure is compared with previously published results and excellent agreement is achieved. The dispersion diagrams of microstrip line on magnetic substrate are computed numerically using method of moments and compared to previous work.
