PROJECT TITLE :
Analytical Expressions for Spatial-Domain Green’s Functions in Layered Media
Accurate and economical formulas for computing spatial-domain Green’s functions are presented during this paper. To use the formulas, we tend to only require a group of sample points of the spectral-domain Green’s operate (SDGF) on an integration path avoiding its singularities and an infinite domain tail path. Since the sampling is dole out for the integrand excluding the Bessel operate, the number of sample points needed is abundant smaller than the numerical integration methodology. This aspect of the proposed methodology proves to be very advantageous for evaluating closed-kind Green’s functions at large supply observer distances. It is shown that the proposed formulas provide accurate results for each the close to- and so much-field regions furthermore a big selection of fabric parameters like lossless, lossy, left-handed materials in addition to multilayered substrates.
