- Abstract
In this paper, two types of nanoplasmonic structures, namely multilayer metallo-dielectric and multilayer-swapped metallo-dielectric structures have been analyzed in context of phase jumps and related phenomena due to the positional swap in the metallo-dielectric block. Phase, reflectivity, and field enhancement plots are also discussed in the angular and wavelength regime. Detailed analysis using circular phase response along with the angled histogram of the phase for both structures provides significant understanding of this swapping phenomenon. Parametric analysis of the metallo-dielectric block has also been demonstrated. Figure of merit defined in complex plane also gives some insight into the performance of the structures.
