摘要：

A new efficient technique is proposed to derive a series representation for the two-dimensional (2-D) Green's function of a planar substrate, A perfectly matched layer (PML) is used to turn the original open configuration into a closed one. The resulting structure is regarded as a waveguide and the resulting-analytically known-discrete set of eigenmodes is then used to expand the Green's function. The method turns out to be elegant and efficient for distances larger than 0.1 lambda away from the source.
