Accuracy of the approximation of the dyadic Green’s functions both in the spectral domain and spatial domain for the planar multilayered uniaxial anisotropic media is verified in this paper. The kDB coordinate system and the wave iterative technique are exploited in the derivation of the spectral-domain Green’s function. The presented algorithm relies on the accurate expressions of unbounded dyadic Green’s function and scattered Green’s function, which are classified into the ordinary and extraordinary waves. Then, the accuracy of spectral-domain Green’s function is proved through the comparison of results between it in the EFIE and it in the MPIE. The effectiveness of the spatial domain Green’s function calculated by the modfied fast Hankel transform method for the planar multilayered uniaxial anisotropic media is verified by the comparison with the results from the Finite Element Method.
