The discrete complex image method is extended to efficiently and accurately
evaluate the Green's functions of multilayer media for the method of momen
ts analysis, The difficulty associated with the surface-wave extraction for
multilayer media is solved by evaluating a contour integral recursively in
the complex k(rho)-plane, With this scheme, the discrete complex image met
hod works in both the near- and far-field regions for general multilayer me
dia, whether open or shielded and lossy or lossless.
