The understanding of the surface plasmon modes supported by such structures and their propagation characteristics may help in explaining this behavior. In this talk, first a simple method [3] to analyze rectangular core apertures in real metals will be presented and then the propagation characteristics of surface plasmon modes supported by single and coupled nanoscale apertures will be discussed. In particular, coupling between two and four coupled ectangular core apertures will be considered. [1]T. W.
