Generalized expressions of Green's function for multiconductor strip lines

In this paper the generalized expressions of the Green's function for multicoductor strip lines are derived from a model of narrow charge source by means of the Fourier transformation. Because of using a charge source with finite width, these expressions, occuring as improper integrals of the second type, are convergent at all the points to be considered, which are, hence, most suitable for numerical calculation in the method of moments. In addition, these expressions may be extended to more complicated structures of strip lines without difficulty.
