    By using the Finite Element Method we visualize the modes of vertically aligned superlattice composed of gold and dielectric nanocylinders and investigate the emitter-plasmon interaction in approximation of weak coupling. We find that truncated vertically aligned superlattice can function as plasmonic nanoresonator with capabilities of spectral control over the Purcell effect and Q-factor. Our second goal is related to an important issue of Finite Element Method convergence when applied to finite-length plasmonic arrays. Analysis of the layered nanostructures with finite extension in all three dimensions is complicated because of the large difference in element size across the modeling domain. In order to be sure that plasmonic modes are properly captured and the Purcell effect is accurately estimated, we perform mesh refinement study using three meshes.
