N2 - This paper presents an approach to tackle the problem of searching for mode poles in the complex spectral plane. Instead of a direct pole-by-pole search, here, we propose an efficient indirect search method that gives 'at-once' all the poles that correspond to the dominantly excited modes in the layered medium. The number of steps in the suggested algorithm is independent of the number or thickness of layers, nor on the materials that can be lossless, heavily lossy, and plasmonic. Thus, this approach is particularly efficient in cases where a very large number of complex modes are excited. The approach leads also to an alternative fast Green's function calculation.
