Abstract :
In this paper a new representation for the Green´s function of a general multilayered structure is presented. This approach is based on an efficient plane wave expansion of the source distribution proposed previously. Using a transmission line model for the multilayer media, the effect of the layered media on the incident plane waves is determined by a transmission coefficient, and the amplitude and phase of each plane wave at the field point are obtained. The total field is evaluated by summing the resultant plane waves at the field point. Using this method, the spatial domain Green´s function for a multilayered media can be obtained easily, without the need for Sommerfeld integration or using the complex image approximation.
