ANALYSIS OF ELECTROMAGNETIC CYLINDRICAL WAVE INTERACTION WITH INHOMOGENEOUS PLANAR MEDIA

An analytical method based on combination of Fourier transform and Taylor's series expansion is presented for analyzing interaction of electromagnetic cylindrical waves with inhomogeneous planar layered media. In the proposed method, constitutive parameters and Fourier transformed electric and magnetic fields of inhomogeneous layer are expressed using Taylor's series expansion. The validity of the method is verified by considering some special types of inhomogeneous media and comparing the obtained results by the presented method with those of other reported methods. The results showed that when Fourier transform combined with Taylor's series expansion, they could provide a powerful technique for analyzing such problems.
