A new systematic procedure for calculating the electromagnetic fields in anisotropic planar multilayer structures is presented. Working in the Fourier domain and utilizing the symbolic computation capability of the Mathematica® package, closed-form expressions for the transformed electromagnetic fields are derived in a straightforward, error-free way. Therefore, spectral Green’s functions can be determined in compact, closed form, with considerable reduction of the calculation time. Using this new procedure, Green’s functions for anisotropic grounded layer and also for biaxial microstrip multilayer structures are derived.
