Semi analytical numerical analysis of plasmonic structures in layered geometries

An upgrade for the efficiency proven electromagnetic simulation tool, Multiple Multipole Program (MMP) is proposed, in order to efficiently analyze plasmonic structures in layered geometries. In this upgrade, a new expansion set, the layered media Green's function, is included in the open source EM simulation package Open- MaX, which contains the latest version of MMP. By this upgrade the advantages of both the MMP and layered media Green's functions are combined and an efficient and robust simulation tool for the analysis of structures in layered geometries in optical range of the spectrum is obtained. In this paper, the fundamentals of MMP and the derivation of layered media Green's functions will be discussed. Numerical results will also be included in order to demonstrate the efficiency of the upgraded method.
