Local field enhancement: comparing self-similar and dimer nanoantennas
Giovanni Pellegrini, Michele Celebrano, Marco Finazzi, Paolo Biagioni
TL;DR
This paper compares the local field enhancement capabilities of self-similar nanolenses and standard dimer nanoantennas, finding that increased structural complexity does not significantly improve performance.
Contribution
It provides a comparative analysis showing that self-similar nanolenses do not outperform standard dimer nanoantennas in field enhancement.
Findings
Self-similar nanolenses do not significantly outperform dimer nanoantennas.
Structural complexity does not necessarily lead to better field enhancement.
Standard dimers remain effective for local field enhancement applications.
Abstract
We study the local field enhancement properties of self-similar nanolenses and compare the obtained results with the performance of standard dimer nanoantennas. We report that, despite the additional structural complexity, self-similar nanolenses are unable to provide significant improvements over the field enhancement performance of standard plasmonic dimers.
