Discrete complex image method for Green's functions of general multilayer media

摘要

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/sub 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.
