TE-TM SOURCE DECOMPOSITION FOR GENERAL UNIAXIAL BIANISOTROPIC MEDIA.

In the present contribution we study the decomposition of a source into transverse electric (TE) and transverse magnetic (TM) parts in general uniaxial, bianisotropic media. We use a spatial Fourier transform with respect to the axial direction to derive the decomposition in the Fourier domain first. In a next step an analytical inverse transform is performed to obtain the space-domain result. It is shown that in general the decomposition of a source that occupies a finite region fills up the whole space. It is further shown that our results contain the previously published results for uniaxial anisotropic materials as special cases. © 1995 John Wiley & Sons, Inc.
