GENERAL SCHEME FOR ELECTROMAGNETIC REFLECTION AND TRANSMISSION FOR COMPOSITE STRUCTURES OF COMPLEX MATERIALS

A time-harmonic electromagnetic planewave obliquely incident on a stra tified composite structure consisting of different types of complex (b ianisotropic) media is considered. A modified invariant imbedding meth od is used to calculate the reflection and transmission, and the inter nal fields are calculated through a Green function approach. A charact eristic feature of the approach is that it is based on a wave splittin g that is not related to the media which make up the composite structu re, but is always defined with respect to a vacuum. Several advantages of this approach are identified and it is compared to other approache s. Numerical results for the co-and cross-polarised reflection and tra nsmission coefficients for TE and TM modes for a composite structure a re presented.
