Abstract

In this paper, a semi-analytical method for the calculation of electromagnetic(EM) fields in horizontal multilayered media(HMLM) with full anisotropy is presented. First, the governing equation was obtained by plane wave decomposition to Maxwell's equations, and the EM fields in the wavenumber domain (WD) were solved by means of eigensystems. Subsequently, a more intuitive derivation of the spectral-domain propagation matrix method based on existing literature was employed for calculating WD's EM fields in the HMLM. Finally, the EM fields in the spatial domain (SD) were obtained by 2-D inverse Fourier transform. To accelerate the evaluation of SD's EM fields, 2-D infinite integrals were transformed into semi-infinite integrals including sine(cosine) functions by Euler's formula, and fast sine(cosine) transforms based on digital filters were introduced. It has been shown that the proposed semi-analytical method can be effectively used to calculate the EM fields in HMLM with full anisotropy through comparison with the existing numerical algorithm.
