Abstract

The discrete complex image method is extended to efficiently and accurately evaluate the Green´s functions of multilayer media for the method of moments analysis. The difficulty associated with the surface-wave extraction for muitilayer media is solved by evaluating a contour integral recursively in the complex k_p-plane, With this scheme, the discrete complex image method works in both the near- and far-field regions for general multilayer media, whether open or shielded and lossy or lossless
